A classroom physics experiment demonstrating Newton's 1st Law- Inertial Properties of Matter. A student uses a broomstick to knock a pie plate off a beaker filled with water. The pie plate supports a cardboard tube, upon which rests an egg. The force of the broomstick hitting the plate knocks off the pie plate and cardboard, but the egg remains unmoved and drops into the beaker of water. This is because the plate and cardboard move so quickly there is no time to move the egg. There is no force on the egg, so it just falls due to gravity. A cool classroom experiment to teach inertia! Experiment done by Wayne, at Montclair State University.
