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.

Q. When evacuated what force is required to separate them?
A. Hi J Brand, thank you for your question. The manufacturer only states that it's hard to separate. A specific force is not specified.


Great value
