multistage verticle collision balls

Postby fannirun » Tue Oct 27, 2009 12:31 am UTC

Im looking for a way to make or buy a multistage verticle collision ball set. Any suggestions?


It is explained fairly well here. The multi-stage vertical collision balls consists of a plastic stick with four superballs of decreasing diameter impaled on it. Place a fifth ball over the top, hold the assembly by the stick and drop it. The top ball will take off skyward as high as 10 m.

Could you just pair up a basketball and rubber bouncy ball?

Yes. Even a basket ball & a tennis ball will demonstrate this effect nicely.

Just be really careful when doing this. The tennis ball gets propelled tangent to the basketball, not straight up. Sound obvious, but when you get nailed in the balls you'll be asking yourself why you didn't aim more carefully. Learned this the hard way.

I know what you mean, but tangent it definitely isn't. (I picture you dropping the balls with the tennis ball right on top the basketball, and then shooting out to the side)

What Tass said.

At least I didn't suggest doing it with a pair of ball bearings, even though they work really well. :)
