10/02: Buckyballs is cool!
A friend got these Buckyballs and they're fun. Each box contains 216 Buckyballs, arranged in a 6 x 6 x 6 cube. They stick together because they're magnets. The magnets are strong enough that you can make a chain with all 216 balls that won't break when you dangle it. Here's the tagline used for this product:
"Imagine a Rubik's Cube that actually makes you smarter; an Erector Set that never stops erecting; a Hula Hoop you don't look ridiculous playing with; Silly Putty that isn't silly; cram it all in a jar, turn the fun up to 11, and you've got BuckyBalls!..."
