Condition :   Excellent   
Principle :   Formation of water droplets with decreasing pressure.  
Area of Study :  Heat and Fluids  
Equipment :   Bicycle Pump, 1 Gallon Jug, Wooden Matches, Distilled Water, Tygon Tube with Stopper. 
Procedure :   Place a small amount of water in the bottom of the jug.  Warm water will work a little better that cold.  Light a match, wait for it to burn down, and then blow it out, and immediately drop it into the jug.  ( The smoke will create the nucleation sites needed for the demo.)  Insert the stopper and twist it in fairly well.  Pressurize the jug with the bicycle pump and when the stopper pops out the cloud will form.
