The design of the SpillNot™ uses the principles of Newtonian physics to keep the liquid in the container. The flexible handle and the location of the suspension point above the cen ter of the tray ensure that the forces on the liquid are always directed towards the supporting tray, even when the tray is in motion. The sideways forces that are usually responsible for spills are not transmitted to the tray by the flexible handle and the radial forces generated during swinging motion only pin the liquid into the container more firmly. An inexpensive demonstration to intrigue students and challenge their analytical powers! Includes activity guide. Shipping Weight: 0.25 lb., dimensions: 5" x 5" x 9". Show more
