A great addition to the key ring of folks around the water.

The self-inflating Key Buoy from Davis Instruments can end the nightmare of keys dropped overboard. Even if your keys are on the Key Buoy, if you drop them into the drink, they sink. But wait about 30 seconds to a minute and your keys come bobbing back to the surface! Once you see that inflated orange tube breaking the surface you have approximately 25 minutes to grab them. (It starts to deflate after about 30 minutes.) I wondered how it worked. The guys at the Davis Instrument booth were happy to explain. When you drop the Key Buoy in the water, a tiny piece of sponge inside the device expands and forces the plastic clam shell to open. When it opens, a tightly folded 14” plastic tube is released. Then a small tablet which contains baking soda dissolves. This creates a gas that fills the tube that floats your keys. The package says the Key Buoy is suitable for items weighing up to 2.8 ounces. That's about as many as 5 keys. Davis Instruments said you can even attach them to other things that often fall in the water like the water fill or gas cap key providing it doesn't weight more than 2.8 ounces. We that in this week's photo shoot for World News Now and it did work. These are single use devices, but cost $7 TO $10. And if it saves your keys, I think you'll say it's worth it! This gadget has been around for a long time, but I figured a lot of people probably don't know about, so I'm showing it again. As reporters say: If you never saw it before, it's a 'new gadget'!
