Carl,
What's the approximate size of the unhappy balls?
Thx, John /TCG
1 inch... They're the same size as the bouncy balls you buy in a gumball machine for a dime or quarter. It's so weird to drop one from a few feet, it just drops and stops. NO bounce AT ALL, it's like dropping a magnet on an iron block. At 5-7 feet, they have maybe a .5" bounce. I'll try them at 15' soon.

If you drop a bouncy ball (which I have tons) next to the 'unhappy' ball, it's so weird.... because they're both seemingly the same and one goes nuts while the other just stops.
Fun stuff, great conversation piece... So, entertainment and isolation in one product... it's a win-win!
