The Diving Jellyfish (Cartesian Diver in the the shape of a cute Jellyfish) will perform amazing hydrodynamic tricks!

Just place him in a bottle of clean water, squeeze the bottle and watch as Jellyfish spins and dives up and down. A fun, engaging way to learn about Pascal's Law of equal pressure distribution in a fluid. You'll be jumping around like Archimedes after a bath and shouting "Eureka!" as you unravel the mysteries of this diving jellyfish.

What You Get

Jellyfish by TEDCO Includes one colored plastic jellyfish. Requires refillable water bottle (not included).

How does it work? A classic Cartesian diver demonstration with a Jellyfish twist. When you squeeze the water bottle, the air inside the Jellyfish is compressed and allows more water to enter, increasing the plastic Jellyfish's density and causing it to sink. When you release the bottle, the pressure drops again. The air in the Jellyfish expands, pushing water out. This makes the Jellyfish lighter, so it floats to the surface.
