How does it work?
Squeeze the soda bottle and SQUIDY swims up and down in the water. The illustrated science activity guide shows how to construct the Cartesian diver and explains the scientific principle behind its action.
What does it teach?
Cartesian divers provide an amazing way to demonstrate and understand the science behind density and buoyancy. Discuss the properties of air and ask your kids to guess why SQUIDY sinks when air is forced into the bottle and floats when they let go.
Not so much

After precise balancing of the amount of water needed in the pipet, Squiddy does float up and down with squeezing.
