  • The SpillNot

    An inexpensive demonstration to intrigue students and challenge their analytical powers. The cup holder won’t spill when carried through a busy café or down a flight of stairs! You can even spin the cord around in a circle without losing a drop — but don’t jerk it!

    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 center of the tray to ensure that the forces on the liquid are always directed toward 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 because the flexible handle and the radial forces generated during swinging motion only pin the liquid into the container more firmly.
