Electronic Bubble Wrap
I've
never fully comprehended the uncontrollable desire some people have to
pop bubble wrap. But in the interest of preserving the world's supply of
packing material, I present to you the Electronic Bubble Wrap keychain. Each
press of a "real feel" rubberoid button causes the device to emit a lifelike
(and I suppose, satisfying) pop sound. But it gets better. Every 100th
press unleashes a random bonus sound instead of a pop (dog bark, cartoon sfx,
bodily function, etc.). Big payoff. $9.99 from the good folks at
ThinkGeek.
