Why not super size your glow in the dark SQUIDY toy? Just imagine the sound of 30 children ooohing and ahhhing with excitement as an eerie green glow emanates from your classroom. Includes materials to make 30 glowing SQUIDY divers. SQUIDY has become a classic science toy! Squeeze the plastic soda bottle and SQUIDY swims up and down in the bottle of water. Children can't help but ask, "How does that work?" The illustrated instructions show how to construct the Cartesian diver and explains the scientific principle behind its action.
What's included?Materials to make 30 glowing SQUIDY Cartesian divers and instructions. You supply the plastic soda bottles and caps.
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.

This was used as an activity for my after school science club. This kids LOVED Squidy! They enjoyed learning about buoyancy and watching Squidy dive and float. Each student brought in a 2 liter bottle and made their own Squidy to take home. One of their favorite activities!

As part of our arctic/polar unit we learned that penguins eat shrimp, fish, and squid...EXPERIMENT!!! The kids loved learning about buoyancy with these fun glow-in-the-dark critters. The step-by-step directions were easy to follow with my 21 third graders! Thanks for another great lesson!
