This activity provides instructions for the world's simplest Cartesian diver using a plastic bottle, condiment package, and water. As you squeeze the bottle, you increase the pressure everywhere in the bottle. The higher pressure compressing the air in the plastic condiment container decreases its buoyancy causing it to sink. Find out what happens when you release the sides of the bottle.
