Condition :   Excellent  
Principle :   Elasticity
Area of Study :  Heat & Fluids  
Equipment :   Rectangular bottles, capillary tube in a stopper.
Procedure :   Fill the bottle with a dark liquid.  Fill the flask full enough so that when inserting the capillary,  several inches of liquid is forced up into the tube.  Squeezing the long side of the flask should cause the liquid level in the capillary to rise.  Squeezing the short side should cause the liquid level to fall.
