Cloud Chamber

PRODUCT DETAILS

Contains a coupon to request a fresh alpha source, used in various experiments including “random events” and “range of alpha and beta particles.” An absorbent blotter on the inner wall of the chamber is saturated with alcohol. The unit is tightly capped and placed on a block of dry ice. The vapor within the chamber becomes super-saturated due to evaporation. When the chamber is brightly lighted from one side and the alpha source is introduced, the condensation trails of the alpha particle may be observed. Instructions included.
