Rubber Mat Air Pressure Demonstration (Gompita-kun)

Demonstrate the force of atmospheric pressure with the Gompita-kun Rubber Mat Air Pressure Demonstration. Place the flexible rubber mat on a smooth, flat surface and challenge students to lift it using the handle. The activity helps students explore how air pressure acts on surfaces and why lifting the mat can be surprisingly difficult.
