one of the single greatest gifts (and curses) to anyone who is a little anal retentive is bubble wrap. a great package protector, but the real joy is popping each and every bubble. dont try denying, i know everyone loved doing so as a kid (or even now). welcome to the future, my friends; electronic bubble wrap is here.
this keychain device has 8 rubbery little "bubble" buttons. guess what happens when you push one? yeah, you hear a little pop. but there is one bonus, every 100th "pop" is not a pop at all, but a silly sound: a boing, a bark, a rude noise, etc.
