Tips	Don’t pump more than 30 psi (white scale in a pressure gauge) – may cause an explosion and personal injury. Also within the box is a hose attachment that can be installed instead of the air valve. Put your thumb over the end of the tube and pressurize the bottle. Release your thumb and the “Cloud Chamber” effect is increased.
