O buoy, O buoy i gone darnit dropped my keys again!
Every so often a gadget comes along that isn't much to look and well, doesn't do much at all but the invention itself is just genius. Well the Waterbuoy does just that. Now Lets say you dropped your keys in the middle of the ocean. O dear, o dear. But fortunately for you, 30 minutes before that happened your lovely wife attached the Waterbuoy on your key ring, now just wait a few seconds and watch your keys float happily to safety. Lovely jubbly.
So how does the Waterbuoy work? Well when the device is submerged in water a little gas canister inside the Waterbuoy is activated. This then fills up the balloon and floats whatever you had hooked on it to safety. And what if this happens at night? If it does, they have kindly added a flashing LED light inside of the balloon. How thoughtful.
So you're wondering what else you can attach to this bad buoy, well, you can attach anything onto it that weighs no more than 1KG (2.2 pounds), if you put more than 1KG on the Waterbuoy the chances of you seeing it again are very slim so please don't attach it to yourself. The Waterbuoy will float for a minimum of 24 hours. Also the balloon that the Waterbuoy uses is surprisingly versatile, it really is hard to pop, so don't worry about any sharks biting it, they will surely be leaving with no teeth (highly unlikely I'm pretty sure its still plastic).
