Diffusion Cloud Chamber

See Visible Tracks in Just 15 Minutes

View high-energy alpha particles, lower energy beta particles, and electrons that are produced from sources of naturally occurring radiation, like radioactive material and cosmic rays. This cloud chamber is an exciting and fast developing demonstration that offers ease of operation and portability. Unlike most cloud chambers, this unit does not use dry ice. Simply connect the unit to a source of cold running water, or use the included pump and a container of ice water for hours of continuous use. All the necessary equipment is built directly into this chamber, eliminating the cumbersome transportation and extra expenses of furnishing illumination or a high voltage power supply.
