Condition :   Excellent  
Principle :   Temperature rise with increasing pressure  
Area of Study :  Heat and Fluids & Planetary Astronomy
Equipment :   Plexiglas box, 200 mL of hot water, wooden matches, 2 gal Ziploc bag, and 2 Liters of ice.

 

Procedure :   Pour 200 ml of hot water into the bottom of the Plexiglas container.  Place the 2 Liters of ice into the Ziploc bag and press out any air.  Light 2 wooden matches and throw them into the box with the water and immediately cover with the bag of ice.  As the cloud starts to form you should see a convection current that moves from the hot water to the ice bag and back down.
