Gravity

To introduce our unit on space, we made a little magic with gravity.  After discussing Sir Isaac Newton's laws of motion, we set up a demonstration and made predictions.  You need to visualize three cups of water beneath a pie pan or tray.  Balance three tissue tubes directly over the cups.  Place three eggs on the tops of the tubes.  I highly recommend using eggs that have been hard boiled.  Now, donning a magic cape and high hat (magic is always such a thrill), pull the tray quickly away.  What happens to the tissue tubes?  What happens to the eggs?  Why?
