Since I've been working on Funda Ball I've written up some rules and measurements and such.  At the moment, a game of Funda Ball calls for the use of tennis balls as the ammo.  

   I'm not super fond of this idea because Tennis balls are for, well.. Tennis.  I've been noodling an idea that I would like to use ammo actually a bit smaller than a tennis ball, biconical (or at least egg shaped), that is about as heavy as a tennis ball (if not a little heavier) and is softer and easier on fleshy tissues.

   I could use some input on this one and I know that there are many devious and clever minds out there.  

   I'll start the festivities...

   When I was messing around tonight I hit upon the idea for a slightly modified Rusty ball.  Normal Rustys are NOT a good choice for this game because they can probably still kill you.  MadSlinger once offered to stand downrange and catch one of them for me to which I stupidly agreed.  To his credit he almost caught the darn thing.  Downside:  It hit one of the fingers he was trying to catch it with as it went by.  By the way it swelled up, we both thought it was broken...  And it's not like I was throwing that thing very hard.  If it would have hit him in the head he might still be in a coma...  Rustys are great when you are throwing them at hard targets.  Even windows stop them with no damage.  But they sure do transfer a lot of their energy to fleshy targets...

   So, my modification was this.  I got a 12’ balloon and filled it up about a little over a quarter of the way full with Silicone.  I tied that balloon off, cut off the tail and started wrapping that up much like a normal rusty.  After I got to the last one, I used some clear scotch tape to secure the last balloon.  Then I got the bright idea to wrap some tape snugly around the middle of the balloon.  This caused the balloon to take on a (roughly) biconical shape..  I would show you a pic but alas, I lost the ugly thing on the roof of my building during testing.

    Test Results:  Out of the few times I got to throw this Prototype Funda Ball, I was amazed at how heavy it felt.  I’m sure that it was lighter than a tennis ball, but the weight seemed much Denser (which it is I’m sure).  There were absolutely none of the release issues I imagined there would be and in fact I managed to hit my targets about 8 out of ten times from 10 meters.  That’s a huge jump in accuracy for me.  The only main problem I noticed was that when I threw it with a lot of power, it did curve easily.  I assume this is because since the projectile is kinda squishy, it is deformed a bit as it travels and therefore ends up with terrible flight characteristics.  I hadn’t had the opportunity for human testing yet, but we’ll get to that (Yikes!).  After all, the point of these is to hurt a bit less than tennis balls might…

   So anyway, let me know what ya’ll come up with!

I think you are going to have the same problem as the origional, the liquid is non compressable and it will still whap you pretty good, I think you will need something hollow.

how about something more akin to mini nerf footballs.  Something like this may or may not need weight added to the center and may or may not need the pointy ends ground down a little.

You can find places like this ( http://www.minithrowballs.com/foam-footballs-c-83.html?osCsid=992300977dacef7164b8ee1c05c99bb3 ) that sell them in bulk.  Heck it even looks like you could get slinging.org and a fundaball logo printed on them.

This on looks like it was born for fundaball: http://www.minithrowballs.com/stress-football-p-179.html

Yeah they do!  That's exactly the thing I was thinking of.  I was thinking that we could inject a small amount of silicone along the centerline to add some weight.

And being belted with a stress ball is going to relieve your tension for sure!  ;D

Somebody has to sacrifice their body to prevent the other team from scoring, those are one of the reasons I picked Dan and Squirrel, they're young, they ought to heal up pretty quick...

LOL.....
I have been nailed by stones before, but never at full power.

Squirrel will probably heal faster than anyone else.
Can I add Jabames and Sasquatch to our team somehow?
LS, for a better version of funda-ball, have more than 2 people up front.

I definetly like filling up a water ballon with something because they are small and can probably travel really fast too, but what would you fill them with? jello? water? saturated cloth? :-/

 Well I wouldn't even try jello.  It contains gelatin which is animal tissue, which rots.  Might smell pretty bad if the projectile broke!  
 
  I was shopping in big-5 the other day and saw something else that might work.  Medium compression tennis balls.  These are usually a different color than a standard tennis ball, and they are softer.  They are generally used on smaller than normal tennis courts.  They feel about the same as far as weight goes and should be a bit less painful to be hit by.  Still not biconical though..

what about paintballs? there are readily available and pretty inexpensive, they are small, they are made to be projectiles for this kind of sport, and you can tell when a target or the general is hit ;D

How about a biconal shaped cloth bag filled with airsoft BB's and a few pieces of styrofoam for compression and shape?  The foam will keep the ends pointed and will compress when it hits something and the plastic BB's will give some weight and also compress when it hits.  The problem will be the manufactoring of enough to play a game with.  Sew and then glue, maybe?

Well a couple of reasons not to use paintballs:

#1.  They are really light little buggers and don't sling very easily.
#2.   they bust on contact, which makes them great for paintball, but not so much for the scoring methods used In Funda ball..

I have thought about playing sling-tag with these though!

Tennis balls seem like they would have the perfect fuzzy texture to hold a nice dose of marking chalk.  There are all sorts of colors available, although some are more indelible than others.  I imagine having a team color loaded into a rock climbers chalk pouch would be a great way to dope a tennis ball in a slingsport situation.

I agree with tennis ball projectile. Wait, rock climbers chalk comes in different colors?
Airsoft bb's are quite expensive, BillSkinner.

marking chalk(the kind used by builders) comes in many different colors, rock climbing/gymnastic chalk is only white from what I've seen.

Commonly, in builders marking chalk, purple is mildest, followed by blue/orange and yellow, then light red, then black, then dark red is usually most indelible.

I imagine you could make custom colors by pulverizing sidewalk chalk.

But you would be able to keep reusing the BB's, they would be on the inside of, basically, a sock.

I think I have an idea..  I may be able to post it later tonight...

I had a look in a local Toy 'R' Us store the other day to see what sort of balls they had in there, and in particular looking for the football style stress ball. They had some there that was listed as 'small', but in my estimation, would be too big to fit in a sling. They were more like a third of a size football.


Mick

Yeah Mick, probably a bit too big.  

But, the Stress Ball idea is sound.  I haven't been able to test it yet but, I have made some research progress.  Remember the T-Shirt Thread?  Well, that thing is coming in all sorts of handy..

Enter the prototype Funda Ball:

http://i1339.photobucket.com/albums/o714/LightSlinger/A3753479-A372-418F-A6F7-D494FB78506B-15063-000010CC2759938F_zpsabbc88ea.jpg

It's not too pretty to look at right now, but it has all the characteristics we are looking for except for one..  Well maybe two..  Accuracy.

The TFB (T-shirt Funda Ball) is the perfect size for slinging.  It weighs maybe a little more than a tennis ball, but it's biconical, meaning better aerodynamics.  Also, it's softer without taking all of it's punch out.  The main problem with this guy is that he flies in a corkscrew type pattern.  It still basically goes where it's pointed, but it may drift a bit.  Another upside to the TFB is that it's pretty easy to throw with a spiral.  In fact, it's easier than throwing a real football bare handed is...  The other downside to this ball is that I think it may have a tendancy to get a little distorted in shape when it hits something.  Not drastically, but seems like the nose flattened a little after a couple of throws..

 This particular ball took up about 3/4 of a ball of T-Shirt Yarn.

What if you made a casing of vinyl in a biconical shape and stuffed it with your T-shirt material, then stitched it closed? A smooth outer surface would be better for the aerodynamics. Come to think of it, you could fill with whatever you wanted. It might also hold it's shape better with a casing.


Mick

you're not slinging over large enough distances to bother with biconical.

For short distances ie: under 100 metres, spherical ammo is best. Same impact no matter how it hits. Which you don't get with biconical.
Same flight characteristics - always.

And much much easier to make.

How about wrapping a golf ball in the t-shirt material ?
That should give you weight, softness and pretty easy to make.

Actually another argument for tennis balls is you can line the targets, and possibly the players, with hooky side of velcro and the tennis balls would stick to them.
Give the players velcro vests and you'd have to hit the torso or the tennis balls wouldn't stick. Which should help stop people going for headshots.

Dunno if I agree about the biconicals.  I can put some pretty viscious spin and drift on a tennis ball inside 40 meters.  A biconical with a smooth surface area should put an end to that kind of shenanigans.

The velcro is a cool idea for the Sling Dodge Ball thread, but it lends a bit of silliness to Funda Ball that I'm not sure I like (for some reason these images of people coated in velcro throwing themselves against velcro walls to stick to them keeps popping into my head.)  Really, the only player that it's important to know about hits on would be the General, and there should be a ref watching him anyway.  

@ MickR:  Yeah, that could work but it might just be easier to buy a bunch of stress balls and inject them with silicone.  It actually took a bit of time to make that prototype.  Maybe it was just cause it's the first one I've made, but I dunno.  I'll have to try and make a few and see how long they take.  For the casing though, I was thinking about the possibility of using shrink wrap.

Shrink wrap might be too brittle, but you may as well try it anyway. Can't hurt!


Mick

I am working on a stuffed-sand-fabric type thing, its sort of like a cornhole bag but different. Will post pics.

I don't think sandbags will work for the same reason that we can't use rusty sling balls.  They will hurt and probably injure.  I experimented with putting a rusty inside of the t-shirt Funda ball.  It hurts.  And I just threw it into my leg, and not very hard.

You misunderstand me. I am making a ball-like thing from sand-fabric- cotton fabric with sand glued to it. Its very soft, but heavy.
I slung one at my friend, it was a half-done 2 oz thing. It left a reddish mark, but no bruising. From 10 yards, medium power.

Ah, I see.   Can't wait to see em!

Hm...have someone tried a heavy footbag king of ammo,I have an experience  with this king of footbags filled with dense plastic pellets. They do fly well and do not cause bruising(as far as i tried with a 2 1/2 oz bag hitting a friend of mine within 20 feet distance with force)

I think tennis balls are still a good idea... I think it's difficult to throw a tennis ball very hard because of wind resistance on the fuzz.   Plus it's an easily attainable inexpensive and somewhat expendable ball that will stay in the fence of a tennis court.  You guys got pictures of those ones you're building?  Or links to pictures?

Now the T-shirt wrapped golf ball idea has some merit... has anybody tried that?

Not yet, but I'm not adverse to giving it a go.  However, like I mentioned earlier, I did wrap up a Rusty Sling ball, which is softer than a golf ball, and with a core that heavy and compact, it was just too hard.

i thought rusty sling ball was a joke earlier... what is it?  i am now guessing that rusty is someones name and not a reference to a level of oxidation

you partially fill a balloon with wet sand, then add several more balloons until you have a rusty ball.

I suspect it loses something in translation as it's one of jaegoors inventions :-)

there are various variations. I found that while they make good ammo. They have a tendency to deform on release if you sling them hard.

how about wrapping a (very) small rock with tape or something? that couldn't hurt TOO much, and the small rock would provide with the weight :D

I would've thought that looking at dogs' balls (no, not those ones) would be a start. I sling foam rubber ones that are the same size as a tennis balls but heavier, softer and go further.

Can't say I've seen those kind of dogs balls before, but I have got a few of the heavier tennis balls designed for dogs. They have a tendency to split after a while. They don't last as long as a regular tennis ball, and the difference in weight is negligable. The only other dog's balls I've come across are the solid rubber ones. They would just about lay you out cold if you got hit with one of those though!  :)

<----He has big balls...Of the tennis kind. He lost his own a long time ago! :o

I just made and tried a Rusty today. These things are downright lethal. I would not want to be on the receiving end of one! I suspect they would easily cause a concussion or break smaller bones. Good for target practice, and the one I made comes in at 110gms, and feels much nicer to sling than a tennis ball. It reads better for release timing, sits better in the sling and hits better on the target.

These are what I sling for the hound. Can't say if they'd be what you're after but I don't see why they wouldn't be suitable. They're heavy duty sponge and are less than a pound a ball when purchased in multiples.

Can you test them on someone?(e.g someone with high pain tolerance and not-so-bright)

I already do. I wouldn't suggest for a moment that my ever-loving girlfriend fits the criteria but that's irrelevant as I always miss.

well, shoot.. If you always miss, how do we know if they hurt too bad?  LOL.

I've been noodling this one for quite some time now and I think it's important that they be slightly painful to be hit with, but not be able to cause any actual injuries.  It's a tall order I know.

I don't think bruises count as injury, so, so long as they don't draw blood or break any of the larger bones, it meets with my approval :)...Not that hat's needed of course. Just sayin'.


Mick

bruises are not good.

Caused by subcutaneous bleeding. ie: you're damaging the blood supply below the skin. Which can lead to more serious conditions.
Ideally you want ammo that won't cause bruising.
But still flies well.

A dense soft foam - like memory foam would be ideal. those soft foam dog balls are actually pretty good.

You just let me know where to send you that large order of cotton wool then won't you... :P I know bruises aren't 'good', but I figured you would realise that bruising does happen in sport  :). I also figure you may be saying that just to cover your backside  ;).


Mick

Think of it this way, hit someone with a pillow, the large surface spreads the force, so no bruise, even if you get knocked off your feet.  Concentrate that same force into a smaller pillow and it hurts, even if there still isn't a bruise.  Concentrae it smaller, it really smarts but still doesn't bruise, think dodge ball smacking you in the head.  Concentrate it smaller and it will definately hurt but still won't leave a bruise.  That is probably the area we are looking for, otherwise the teams will just have somebody stand in front of the target and block shots with their body, which they won't do if it hurts.  But they will still be able to catch the ball, think softball with those soft balls that grammer school kids used to play with.  You didn't need a glove but you didn't want to get hit by a line drive, either.

I wouldn't suggest anything like memory foam because it will deform upon release which would probably cause horrible accuracy

Some deformation under an excessive amount of force would be beneficial in a setting such as this.  It would keep a player from cranking out injurious kill shots... or at least strongly affect the accuracy of said kill shots.  Think of calibrated deformity like something akin to a restrictor plate in a nascar race, or a whiffle ball in tee-ball.  Every sport has safety elements in place to keep participation up.

well I was mainly thinking of the memory foam as a final layer over a more stable centre.

Say wrapped round the foam dog balls. It would give a bit of extra weight and hopefully spread the impact a bit more.

The idea I'm most interested in trying out would be he following:

One of those football shaped stress balls with a bit of the center cored out and filled with caulking silicone.  The silicone is soft and pliable even when dry, but pretty dense and heavy.  We use it to make "Sili-balls" when we play sling golf at the parks ("sili-ball" = tennis ball filled with silicone) It turns a tennis ball into something that you can really launch downrange.  (Who says you can't throw a tennis ball further than 70 meters?!  Ha!  Take THAT physics!)

Damn it, now I'll be spending tomorrow implanting my balls with silicone just to make them more interesting to play with!  ;D


Mick

It is going to take a long time to dry, the rubber walls wil keep whatever keeps the putty soft in the putty.  You may want to punch a few holes in the tennis balls to let it evaporate.  Or put it in a car parked in the hot sun.  Put them on a sheet of news paper in case the putty starts dribbling out from the heat.

Something slightly larger than a baseball would probably be good, it would have a larger surface area to spread the force of the impact out.  And you can make a split pouch of your favorite design to handle it.  Plus, it should help cut down on the range so you won't spend so much time chasing balls that go off the field.  It also will help stop someone from hoarding ammo, you won't be able to carry but two or three.  It also means that the guys in the back have to be pretty good slingers, instead bench warmers that you let play.  So, two guys in back with fairly long slings, the two guys up front with shorter slings.  And the general with whatever length he wants.

Actually, we thought this might be a problem too, but it doesn't seem to be.  We fill a tennis ball with the Silicone and let it set overnight.  By the next morning, the silicone at the hole has completely dried and sealed the hole up.  We haven't run into any balls leaking un-dried stuff out yet, but who knows?  And, I'm not kidding..  Those balls are super easy to throw and go pretty far.  We actually had to stop putting so much in them because if they were too full (and therefore too heavy) we found ourselves overshooting the targets pretty regularly, and with little effort.  It was TOO easy, LOL.

Did you crash-tested them against some wall to see the shock resistance ?

And how does it feel when you're hit by one of those in comparaison with normal TB ?

Well, I've never been unfortunate enough to have been hit with one.  I imagine it would probably cause some grevious injuries.  They are pretty heavy and don't feel like they would be very forgiving..

So they are bad choice for Funda Ball... Back to the lab !

Oh yeah, they were never a consideration for Funda ball..  The sili-balls are strictly for sling golf...

So, it's been nearly a couple of years on this topic since the last post...  Has anyone found a possible candidate for the Funda Ball?  I still have yet to give the nerf ball with a sili-core a try, but I think I will give it a go this week.

Seems like the best candidate so far is really just a standard tennis ball, but I had a crazy idea.  I wonder if it would be possible to cut a shape out of a tennis ball that would allow you to collapse it into a biconical shape?

i have cut a tennis ball and formed it into that shape sorta, it ends up looking more like a taco then a bioconical shape. ;D

Hmm..  Tacos don't strike me as being aerodynamic, LOL. ;D

Yeah, we should try that... I wonder if that might actually work.  :-?

My only thing that I have to say is don't use tennis balls, because if you hit someone they will probably pass out, in fact one of my friends was slinging past one of my other friends and he released a little to late and it hit him in the neck, short story is that he is okay but the only reason that he's alright is because he is a karate instructor so he can take a hit, anyways he almost past out, he couldn't breath for a few seconds, and remember that was one of the tennis balls going 120mph and hitting him on the neck. so moral of the story is don't use tennis balls, unless you want to pass out get a welt and be injured

Alright, so an update.  I finally found some time for the sili-core nerf ball experiment. 

    Fail...

    The silicone I injected into the football did seem to add some weight to it, but that was the only good it seemed to do.  The accuracy problem was not helped at all by the extra weight.  The problem with the nerf footballs is that (on medium to strong throws) they collapse a little bit and distort during the throw.  This causes them to fly in a corkscrew fashion, which does not lend itself well to accuracy...

*Sigh..*  Back to the drawing board...

Give it a shot and let us know!

I've tried using the ones with the tails and for the most part my sling ended up grabbing the tail and ripping it out of the main ball, sadly. :(

from the very few times I do remember doing it, it went well. the tails did stay on, the distance wasn't to bad. I will try again.

I'm thinking about experimenting with large "weighted" marshmallows. jumbo marshmallows don't hurt a bit when slung, but they skew off into strange random arcs. They also don't go very far (15m-ish). Perhaps a silicone center in a customer shaped stale marshmallow - like material?

or padding simular to paintball gear, but designed like old armor. The teams can choose a uniform armor style and color.

Another Idea struck me as I was watching late night television a couple of days ago.  There is the awesome stuff called Flex Seal.  It's basically liquid rubber in a spray can.  Now, though, you can get paint cans full of it and pour it into molds!  And when it dries, it looks pretty spongy, but also dense.  Might be the perfect stuff.   I was thinking about trying to make two half bi-conical molds, suspend a golf ball in the middle of them (cause I'm pretty sure it'll still need a bit of extra weight) and glue them together with some sort of epoxy.  Should come out with a nice little football shaped thing with a golf ball center.

Sound pretty genius to me. Let me know how it turns out. :)

What about using a silicone outer layer shaped like a football approximately a quarter an inch thick. Then filling inside with smaller balls, silicone round balls, of perhaps the size of a cheerio or a airsoft bb.  The outer jacket would be for shape in the inside little BBS would hopefully defuse shock upon impact.

Cross section of what I was thinking about.

recon you could do it with that stuff

Yes your link on a different thread is what gave me the idea.

yeah i had a idea like yours from that i was just worried if itd me like a bouncy ball when it hit and jump off somewhere but the shot inside might keep it from bouncing to much
