55 Explanation When you release the closed end of the tubing, the jar and rock sink in the water. When you blow into the tube, the jar and rock rise up in the water and ﬂoat to the surface. In this project, you have built a simple diving bell, a bell- or bucketshaped container that traps air inside when it’s put in water upside down. When the jar and rock are ﬁrst placed in the water and the tube is pinched, the air pressure in the jar is equal to the pressure of the water in the tub, and your diving bell ﬂoats.
