A practical vacuum / pressure demonstration set consisting of two plastic, 10cm diameter hemispheres.
Each hemisphere has a wooden handle firmly attached to it. One of the hemispheres has a raised edge to hold a rubber seal, while the other hemisphere has a stopcock for attaching to vacuum tubing. When the hemispheres are pushed together and evacuated using a vacuum pump they are hard to pull apart. Get 2 students to pull, then open the stopcock to let air in and the hemispheres will separate easily to the surprise of the students.
