Take a test tube of good quality glass material and put a small amount of water in it. Place a stop cork at the mouth of it.
Now suspend the test tube horizontally by two strings or wires as shown in the figure on next page.
Heat the test tube with a burner until water vaporises and the cork blows out.
Observe that the test tube recoils in the direction opposite to the direction of the cork.
