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.
