This durable, thick rubber mat has a simple design that demonstrates a powerful concept: atmospheric pressure. Pick up an ordinary flat lab stool or try to lift the mat off a table, which is nearly impossible. Show how suction cups stick because of the pushing force of air, not from a pulling “suction” force. Explore additional physics concepts such as surface area, force, vacuums, and pressure.

BICYCLE WHEEL

Item AR-630

This Drinking Bird works using properties of thermodynamics, converting thermal energy into mechanical energy. Fluid inside condenses from the evaporative cooling of the water off the bird’s beak, making it top-heavy and dunking it back into the water. The condensate rejoins the liquid pool in the bird’s bulb, and he tips up again. The process continues indefinitely.

This product, also known as a light mill, consists of a set of vanes. Each vane is shiny on one side, blackened on the other, and mounted on a spindle in an evacuated glass bulb. When exposed to the sun or other intense light, the vanes begin to rotate. By studying the rotation intensity, students can measure electromagnetic radiation and witness an eye-caching demonstration simultaneously.
