It really takes a lot of support to keep from rupturing the little fella when you dial in the power during that part of the stroke.
I have tried to do this before, and I'm sure others here have too. You are right about the support! I made a quick sling out of an old t-shirt (I think it was jersey-knit cotton, like most t-shirts), and paracord from and older sling. It had plenty of support, but the balloons still popped in mid swing. I'm sure it's do-able, with enought time. I only spent 30 or so minutes trying before switching to a different sling and tennis balls to stay drier.
Ideas to make it work:
Make sure the sling cups the balloon as much as possible, so it doesn't flatten out too much.
Don't fill the water balloons very full (I tried this, and it didn't work unless the balloons were ridiculously small)
Don't sling at full power (for me, this robs water balloon slinging of all purpose)
Use a long sling (might limit centripetal force for the same velocity)
Accelerate the balloon as slowly and evenly as possible (I favor a single spin, but two spins might help)
