Material:

Two shot glasses or small short glasses

one egg

a table top

Future Quicktime Movie and photos of the demo to go here!

Procedure:

Place the egg in one of the glass and then place that glass on a smooth surface (table top). Place the second glass next to first leaving little if no space between the two. With great force, blow directly down on the egg and move it from one glass to another.

Questions:

How can I move the egg from one glass to the other without touching either glass or the egg?

What caused the egg to ìjump?î

How can this idea be used when holding an umbrella?

Rationale:

The egg leaped out of the glass due to an updraft of air pressure created by blowing into the cup at an angle. Because of the angle at which you blew into the cup, the air flowing over the egg formed an area of low air pressure, which caused the egg to move upward into the air in the room. The air current from the cup met the air current in the room and caused a low pressure flow, which, in turn, caused the egg to travel downward into the second glass.
