Submergency Pool Game

Our Submergency Pool Game creates a high-energy contest of aquatic search-and-retrieve.

First, set the depth to which you want the sphere to sink.

Then compete with friends to see who can find it first.

Once the built-in timer expires, a bright flashing light activates and the sphere's location is revealed.

• Adaptable to any level of swimming ability

• Light blue color blends in with the water and adds to the challenge

• Sphere can be set to any buoyancy by twisting the top and bottom, and can float, sink, or suspend itself at a chosen depth

• Timer can be set for up to a 90-second challenge

• Game entertains any number of players

• Recommended for ages 6 and over

Now don't get all upset, those of you who didn't make the age cut — we can still have a fine time in the bubble-filled bathtub with this fun toy.
