Diving Cartesian Jellyfish
Diving 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 Newton's Laws of Motion. 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. Model number 12090. Includes one coloured 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.
