Cartesian Diver Super Kit

by Unique
SKU 50084
What is a Cartesian diver? It’s an age-old science experiment that demonstrates the properties of air: 1) Air has weight; 2) It occupies space; and 3) It exerts pressure. Place the diver in a plastic soda bottle full of water and the diver floats. Seal the bottle with a cap, squeeze the sides and the diver sinks to the bottom. Release the sides and the diver floats to the top. Enough supplies for 9 investigations. Kit makes divers, retrievers, helicopters and more. Fun for all ages, especially 10 and up.
WARNING: CHOKING HAZARD - This item contains small parts. Not for children under 3 years.
