MAGDEBURG HEMISPHERE METAL 75mm d

• MS0251-01

Used to demonstrate the power of atmospheric pressure.

Procedure:
Place the two Magdeburg hemispheres together tightly and close off the valve.
Attach one spring scale to each hemisphere, then use the spring scales to pull the hemispheres apart.As you pull, the scales will show the small force you use to pull them apart.
For the second part to this demonstration, place the two halves together and open the valve. Place the vacuum pump over it, pump the air out of the sphere, then close off the valve again.
As before, hook the two springs to the hemispheres and pull. This time it will be harder to pull the two halves apart, and the scales will show the greater force of your pull.
