Vacuum chambers are used by physicists for a number of different reasons. In a vacuum chamber, the air is completely removed, creating an environment in which normal planetary pressure does not exist. Many computer components are made within a vacuum chamber. A homemade vacuum chamber can be used by computer hobbyists to create certain components or it can also be used to explore the properties of space by placing common objects in the chamber, vacating the air and observing the results. Many objects will expand when placed in a vacuum chamber, though the effects of the vacuum will not affect every object that is subjected to it.
How can you create a vacuum chamber out of things that can be found aroundthe house?
