Hello,

I am hoping fellow ASTC members can help me locate a source for bouncing
balls.

At the Denver Museum of Nature and Science we perform a Liquid Nitrogen
demonstration multiple times each day. As part of the demonstration we
freeze a hollow bouncing rubber ball and let it shatter. Our current
source for bouncing balls no longer manufacturers the balls we use. We
have a supply for a couple more months but after that we will be out. 

I would think other member science centers perform similar
demonstrations. I am hoping someone knows of a source for inexpensive
hollow bouncing balls. If you can help please contact me at
