Location: Cabinet 3, Shelf 1

Description: The demo room has an assortment of glassware. Most of this glassware is not tied to a specific demo, but can be used as needed.

Glassware of different types

Keywords: Liquid, Measure

Location: Under stairs, back of lower floor of demo room.

Description: When assembled, this frame has a volume of one cubic metter. This is useful for discussions of the metric system, density and air pressure. There are a million cubic centimeters in a cubic meter.

This is useful for the measurement of the density of air demonstration. One cubic meter of air at atmospheric pressure has a mass of about 1.3kg.

Description: This electrically powered, portable vacuum pump can be used for a variety of demonstrations such as the role of air resistance in the motion of falling objects, finding the density of air, demonstrating the large value of atmospheric pressure, or how sound depends upon air for propagation. The box around the pump is held in place with a “T” shaped pin that is released by depressing the button in the center of the pin. When the box is secured in place, the pump can be pulled along by a wire strap with a handle.
