(1) A cloud chamber experiment is described, in which the angular distribution of secondary particles produced in nuclear interaction by high energy cosmic ray particles with paraffin has been studied.

(2) In an updated version of a cloud chamber the researchers are recreating the Earth's atmosphere.

(3) Small mixing cloud chamber with liters cubage has been used in the observation of the nature ice nuclei and the detection of the nucleating effectiveness of artificial ice nuclei.

(4) It was an adaptation of Wilson's cloud chamber, filled with nitrogen gas.

(5) The number of ice crystals generated from lg liquid Nitrogen was determined in a cloud chamber.

(6) Consequently, the thermally generated particles cause many droplets to form into the cloud, which is then detected by the measuring system of the Cloud Chamber.

(7) The main evidence for the validity of nucleation theory rests on its ability to predict closely the critical supersaturation for most liquids in cloud chamber experiments.
