The airtight logic behind the project is this: Aside from being terrific packing material, bubble wrap is one of the most entertaining toys since the cardboard box. There is, however, one major problem with the stuff. Once you've run out of bubbles to pop, you're left with a sheet of flaccid plastic, and who wants that? Infinite Bubble Wrap solves what is almost certainly one of history's greatest problems.

IBW is a small keychain with eight buttons and a speaker on the back. Click one of the little rubber buttons, and the speaker emits a popping sound. It's quiet and it doesn't actually sound much like a bubble in real bubble wrap popping, but these first-generation products are often problematic. That's what I get for being an early adopter.

Pop enough bubbles in succession, and the keychain emits different surprise noises. Sometimes it's a dog barking, other times it's the sound of a doorbell. I'd list all the sounds I've heard so far, but where's the fun in that?

That's pretty much all there is to this little device. It sounds dumb--and it kind of is--but at least for some people (my guess is those who fall within the category of Obsessive Compulsive Disorder), it's addictive.

Bonus points for the incredibly cool packaging, featuring Japanese children so enthralled by the device that tears stream down their faces.
