PUN AND PHILOSOPHY.

The Hercules-Rarllsh Trick—An Illustration of Atmospherto Pressure. We poor human beings would infallibly be crushed by atmospheric pressure if our bodies did not contain elastic fluids of the same volume of pressure, which establish an equilibrium. If we destroy this internal pressure by creating a vacuum in a recipient we can demonstrate the effects of atmospheric pressure., This can be shown in a very simple way by cutting a common radish in

halves, hollowing the interior slightly, then rubbing it slightly upon a dinner plate. In a moment you can lift up the radish by the tail and the plate with it, for the plate will adhere as tightly as if the two objects were pasted together. This is known as the “hercules radish trick. ”
