Use your hand instead of the sheet rubber,and suck out all the air you can. Turn your hand overand in every direction. If the experiment is well done,the Apparatus will not fall off.

Wet a jeMube rubber cap,squeeze it with your fingers or teeth, andpress the tongue against the ojjeuend. If well done, you cannotshake it off. Inference. Why ? Exp. 42. Fill the Apparatuswith water, and tightly insert the ^^^? Exp. with all the holes open, after which plug them witli the shot. Though the stop-per may be easily twisted around in the Apparatus, it ispulled out with great difficulty. Inference. Why ? Exp. 43. Wet the inside of the tube and wrapping onthe piston-rod. Pull up the piston. Inference. Why does water follow it in the tube ?. 34 INDUVTlVE ruYSICS.
