Air Pressure Cups (FM-3603)

FM-3603 Air Pressure Cups

A striking demonstration of the famous 17th century experiment with this simple, modern a variant of the old equipment to illustrate without a vacuum pump, the enormous force of air pressure. Two near-hemispherical rubber cups, when held together face to face and squeezed to force out the entrapped air, it becomes surprisingly difficult to pull them apart. Each hemispherical cup is about 75mm in diameter and has two finger handles to assist in pulling them apart, and two release posts for releasing the inside vacuum.
