Remember the submarine toys you used to find in cereal boxes? This little submarine works the same way. Powered by Baking Powder (not baking soda), it dives and surfaces just like a real submarine. As the Baking Powder reacts with the water, carbon dioxide is produced. This gas forces water out of the submarine decreasing its density and allowing it to surface. This is much the same way a real sub surfaces by purging its ballast tanks. After the sub reaches the surface, the gas bubble is allowed to escape, water takes its place, and the sub dives again. Approximately 4.5" long and wonderfully detailed, this is a great science toy for discussing buoyancy, density and the production of CO₂.

Demo Tank

This narrow tank is perfect for demonstrating float and sink, pouring gas from one container to another, growing Alligator Gro-Beasts, and so much more.

Density Paradox (set of two)

This is an awesome discrepant event for your most advanced 'density' students! Great for demonstrating how temperature can affect an object's density!

Fortune Fish (package of 144)

A very thin piece of red cellophane in the shape of a 3.5-inch long fish, this amazing innovation twists and curls when placed in the palm of your hand.

Large Gro-Beast Alligator

These Gro-Beast reptiles start at about 3 inches long and grow to over a foot long when placed in water!
