Perhaps the greatest tragedy to befall a water sports vacation is when your keys slip out of your pocket and disappear deep into the waters.
Naturally, some bright inventor has designed a way for this to never happen again.
The Key Buoy is a small key ring device that automatically inflates and floats to the surface shortly after hitting the water. It is powered by sodium bicarbonate and tartaric acid which combines to inflate a bright orange, 14 inch tube.
Hmmm… So what happens when the Key Buoy is in your pocket and it rains?
