Eisco Labs, Pair of Industrial Suction Cups Features

• Contains a pair of suction cups with handles (also known as Magdeburg Hemisphere), Finger hole diameter is 1 inch.

• When one suction cup is stuck to a flat smooth surface it can take up to 26lbs of force to separate it from the surface (with maximum adhesion)

• Diameter of suction cup is 3.25 inches (slightly compressed), each half is 2 inches tall

• Great for fixing dents, holding a surface, or doing a science education vacuum experiment

• When suctioned together a minimum of 100 newtons (22lbs) is required to separate them

Demonstrates the force of air pressure without a vacuum pump. In this modern variant of a famous 17th-century experiment, student place the edges of two hemisphere cups together and squeeze them, forcing out the air between them. In a tug of war, students try to pull the cups apart, surprisingly difficult task. Each of the 7.5 cm diameter rubber hemisphere has a 2-finger tug handle and 2 release posts.
