GadgetMadness: We find the coolest gadgets first

We love uber-specialized gadgets that allow a very small group of people to be prepared for a worst-case survival scenario. Take the Key Buoy, for example. First off you'd need to be close to water to take advantage of the "H20 activated" keychain buoy that inflates when your keys hit the water. Narrowing it down further, lifeguards and scuba divers need not apply - we need people on boats for the key buoy to be effective. Next, we need clumsy people on boats who are still on their boats and not in the water being eaten alive by great white sharks or rabid manatees.

So, if you work close to water or on a boat and constantly find yourself dropping your keys overboard, look no further than the key buoy. It will keep your keys from drowning for up to 40 minutes - your keys will breathe a sigh of relief.
