Sometimes the simplest experiments leave the biggest impression! Introduce young chemists to the Cartesian Diver by having them make one of their own. Use the Diver to further their study of liquids and gases, as well as compression.

An experiment to determine if either a regular or a diet can of soda will float or sink when placed in water, and what causes this.

In this experiment, you test whether two different bowling balls will float or sink, then determine the density of each of the balls to see if they are less than that of water.

Use a condiment packet as a Cartesian diver to show how pressure changes cause the "diver" to float, sink or hover.

An experiment in buoyancy which involves making raisins float by using carbonated soda pop. Students then try the same test with other materials. Instructions for making one's own carbonated liquid are also provided.

Learn about density in this hands-on science experiment. Includes full list of materials, procedures, and scientific explanation of what makes an object float or sink. [PDF]

A simple experiment in buoyancy where you discover how to make a packet of sauce or candy float or sink at will, and why you are able to do this.
