This robustly constructed inertia demonstrator works reliably every time and is a great improvement on traditional versions of this classic experiment. A steel ball rests on a thin metal card on top of a pillar, and a spring-loaded catch is mounted next to the pillar. When the catch is released, a piston strikes the edge of the metal card sharply. The card flies out from under the ball, which remains in place on top of the pillar due to its large inertial mass. The card is tethered to the aluminum base for easy recovery after the experiment.

The design of the Spillnot uses the principles of Newtonian physics to keep the liquid in the container. The flexible handle and location of the suspension point above the center of the tray ensure that the forces on the liquid are always directed toward the supporting tray, even when the tray is in motion. Sideways forces usually responsible for spills are not transmitted to the tray by the flexible handle. Radial forces generated during swinging motion only force the liquid into the container more firmly. An inexpensive demonstration to intrigue students and challenge their analytical powers! Includes activity guide. 5" x 5" x 9". Weight: .25 lbs.

A very ecconomical apparatus to demonstrate that light and heavy objects fall at the same rate / accelaration in a vacuum. Apparatus consists of a 36" (910mm) long x 2.25" (55mm) diameter, transparent tube with a stopcock mounted in a rubber stopper on one end, and a solid rubber stopper on the other end. Supplied complete with a 13" long vinyl tubing for connection to a vacuum pump (not supplied), a metal disc and a feather.
