I always thought that after looking at the ball you blew up, it kinda looked like a kidney

 

It was like this semi-liquid/putty that came out of a tube. You would roll it into a tiny ball and and stick it on the end of this plastic straw. When you blew into the straw the stuff on the end would blow up like a balloon, then the stuff would kind of dry so you supposedly could handle it.

 

Yeah, but soon after handling, a little part that wasn't as dry as the rest would stick to your hand and you'd be pissed as everything that the little balloon that you just blew up is now shriveling in your hand. The stuff smells pretty much like rubbing alcohol.
