- Students can now safely produce a vacuum in a small bell jar right at their lab stations. By reducing the pressure in the micro-scale bell jar, they can expand a balloon, boil warm water, and even transfer liquids from one pipet to another. They can watch a marshmallow or shaving cream increase in volume as the pressure is reduced and learn about how extremely low pressure affects the world around them.
