Operation Instructions

Instructions: 
The Magdeburg hemispheres plates are set of plates which fit together along an air tight edge (the o-ring). One plate has a fitting which allows it to be pumped down by the syringe vacuum pump and sealed off. Hook up the syringe to the fitting and make sure the valve is open.  Pump down the set, close the valve and then disconnect the pump attachment. 

Now ask one students to come up and try to pull apart the plates... They can't. Release the valve and the plates should then pop right apart.
