I have a silly idea for keys. Which I guess I can just talk about because this is a distributed blockchain lol. The idea is simply to hide an airbag about the size of a softball when inflated, inside a keychain that's no bigger than a large tums. One which remains tiny all the time, unless it's actually submerged for more than three seconds, at which point, it pops open using a tiny co2 charge, and makes sure you don't lose the keys to your yacht at least. I'm so close to getting to 420 ideas and publishing. Each idea is supposed to have a little narrative. With this one it's super easy. Alx
