An inexpensive demonstration to intrigue students and challenge their analytical powers! The design of this cup holder 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 center of the tray, ensure 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. Includes activity guide. 4-3/8 dia. x 8 H (excluding handle). Grades 7-12.
