Learn how to keep water from flowing through a screen.
At first glance, you might think that you’ve seen this science demonstration attempted by a friend. A glass jar is filled with water and covered with an index card. The whole thing is turned upside down and the hand that is supporting the index card is pulled away. The card appears to be stuck to the inverted jar of water. In and of itself, this is a very cool trick, but in this version of the experiment, things get crazy. The inverted jar of water is held over the head of a spectator and the index card is pulled away! The gasps are audible . . . someone screams in anticipation of the water falling from the jar only to drench the poor spectator. To everyone’s amazement, the water does not fall. It’s suspended in the jar, literally floating above the spectator’s head. The card is replaced, the jar is returned to its upright position, and the science magician pours the water back into the pitcher. The only sound you can hear is that of people scratching their heads. Amazing!
