Waterbuoy – keychain balloon retrieves your keys and devices if they fall into the ocean


Waterbuoy. Interesting little keychain product contains a self-inflating balloon which pops open and floats your chattels gently to the surface if you suffer a sudden immersion situation in, say, the nearest ocean or lake. It’s a one time use product only, but since it can support up to a kilogram for over 24 hours, and has a high intensity LED beacon to make location easier, it could be a majorly sensible investment for sailors and landlubbers alike. £14.95.


 This clever little device contains a high-strength rubber balloon that can lift up to 1Kg and automatically inflates within seconds of hitting the water, causing the whole shebang to rise gently to the surface. And thanks to a high-intensity LED beacon that’s visible from over 250m at night, you can spot it bobbing about and retrieve your keys/valuables with ease.

  • The guy who invented this was on Dragon’s Den a few months ago. He got the money, if I recall – it’s a nice bit of design and he was very impressive. It’s good to see it hitting the shelves

  • What’s wrong with the plastic bubbles that boat owners have been putting on their keyrings for the last 40 years?

    This seems a little too complicated for a very simple idea.

  • Well we all have more stuff these days, don’t we? As the title says, it’s not just for keys but for anything larger – purses, personal devices, boxes. 1kg worth of buoyancy is quite impressive for something so small. Agreed, the little plastic bubbles are fine for keys alone, but many people want more.

  • A cool idea, but I really don’t see me needing to keep a kilo floating…

  • Technology: Depends if you’re from Colombia, (boom, boom) :-)
