This invention is directed toward a device which provides buoyancy to objects with negative buoyancy in water. The invention comprises a water-sensitive trigger which, when activated, causes a balloon to inflate, causing the object to float upon the surface where the user can then easily and safely retrieve it, through one of two mechanisms: first, a compressed gas is allowed to exit a canister and enter a balloon, second, one or more substances which, when mixed with water will produce bubbles are exposed to water and the balloon is filled with bubbles from the chemical reaction. There are a number of variable characteristics, including canister size and shape, trigger fuse length, balloon configuration, and housing material that allow a user tremendous flexibility in selecting a proper size of the invention for the user's intended purpose.

What I claim is: 1. A device for providing buoyancy to a negatively buoyant object, comprising: a lower casing, means of maintaining pressure, a plunger, a bobbin designed and manufactured to disintegrate under a certain condition, a casing, a canister filled with a compressed gas, an O-Ring, a syringe, a balloon casing, a balloon, and an end cap, where, when the bobbin disintegrates, the means of maintaining pressure causes the canister to move up and be punctured by the syringe, whereupon the compressed air in the canister exits the canister and fills the balloon, thereby providing sufficient buoyancy for the object to float.
