Today I found an interesting item at a local toy store. Here it is, in 50 seconds:
I believe it is a Play Visions Mondo Hi-Bounce Pearl Water Ball. Although a toy for kids, it could be repackaged in unbreakable glass with a nice stand, then sold as an executive desk tchotchke. I’ve got to think it would outsell the likes of Newton’s Cradle (the contraption with hanging metal balls, knocking each other back and forth). After all, chaotic turbulence is so 21st century.
