A must-have for any experiment that requires a vacuum!
This Surface Plate is 200 mm in diameter and comes with three small pads fixed to its bottom to ensure it rests evenly on your work bench or any other surface. It’s designed to work with a bell jar, Mason jar, or any similar vessel that will allow you to create a vacuum or low-pressure environment.
Find out what happens to the ringing of a bell inside of a bell jar when a vacuum is created! Watch a shelled hard-boiled egg get sucked into a pop bottle! Or see what happens to a marshmallow when all the atmospheric pressure is removed!
