INCLUDES: 21 gold, silver and bronze-colored rings, a crystal-clear water tank, and 4 interchangeable plastic panels featuring fun deep-sea scenes! Also includes color instructions. No batteries. No Wi-Fi. No Problem!

ENGAGING AND ENTERTAINING: Help Poseidon, God of the sea in Greek mythology, recover his powerful rings from the bottom of the ocean!

PLAY ON YOUR OWN OR WITH A FRIEND: Submarings includes two buttons for dual-action control or to allow for two players at once.

JUST ADD WATER AND PLAY: Recover all the Submarings using fluid dynamics! This challenging game is endless fun as you try to get all the rings on the pegs through the power of water! And, can you add the same color rings on each peg?

This fun game works by using a very cool principle of science called "Bernoulli's Principle," which is related to fluid dynamics, or the movement of fluid. In the case of this game, the fluid used is water.

When you push the buttons on the base, the force from your finger creates water pressure within the tank which is proportional to how hard you press the buttons (pressure = force/area). The pressure pushes on the water molecules and gives them speed to move (kinetic energy). As the water molecules move, they are forced through a narrow nozzle into the tank, which causes them to move even faster as there is less space for the molecules to pass through.

Therefore, the harder you push the button, the faster the rings will move! Pretty cool. huh? Watch the path of the rings to give you an indication of what's happening with the water. With enough practice, you'll know how much pressure to apply to get the rings on the pegs!
