Self Inflating Key Chain

The KeyBuoy is ideal for those either involved in water sports, or who are prone to dropping keys down the drain. The KeyBuoy is a self inflating key chain which when it comes in to contact with water it inflates a bright orange buoy to keep your keys near the surface of the water and visible for about 40 minutes. It is only good for use once, but does only cost $6.99 which isnt a bad price at all. I personally would buy two for my self so I could test one and use the other correctly.
