Waterproof? Guess We'll Find Out In The First Rainstorm
-
An Israeli inventor has come up with a cardboard bicycle: fireproof, waterproof, durable, and very cheap, about $20. He worked for years to come up with cardboard strong enough to support a human's weight, and he says he's got it now. And the tires are solid, not inflated, so they can't go flat. They look a little goofy, but... for $20... (Chicago Tribune)
