The SwimWays Toypedo is a hard rubber torpedo-shaped diving toy. After a couple of tries you will figure out how to toss this toy underwater and watch it glide across your pool every time. Kids and adults both will love tossing the Toypedo back and forth, making gravity defying grabs in the pool. The Toypedos in this set of four all feature unique colors and number values to let kids create their own games to play. We do not want to bore you with the physics behind this pool toy, but it was designed around the complex hydrodynamic principals of nuclear submarines.
