Students experiment to examine high and low pressure areas. They investigate why a high pressure area seeks a low pressure area.

Young scholars develop and test their ideas about air pressure and vacuums by conducting several investigations into the movement of fluids in tubes.

A bell jar is evacuated to show the properties of a vacuum and air pressure. Pictures and a description of how to perform the demonstration are given.

Rolf Landua and Anais Rassat explain the science behind vacuums.

Try this hands-on experiment to figure out how a vacuum cleaner works. Find out about pressure by using drinking straws.

As part of a larger exhibit on science and the history of scientific instruments, this site examines a painting by Joseph Wright and its connection to the scientific studies of the vacuum. The painting, which is accompanied by a...
