Join your friends at Hancock Park District to create your own cartesian diver. This fun toy is an experiment that demonstrates the principle of buoyancy. You will create a diver that will look like a fish, an otter, or a turtle and then place it in a bottle of water. With a simple squeeze, you will cause your diver to sink or float. Have fun playing with this toy while learning about the science behind it.

Meet at the Discovery Center Porch.  This free program is for children ages 6-10, registration not required.
