Fill a test tube with a mixture of a small amount of ink and very hot water.
Holding your thumb over the mouth of the tube, gently lower it into the tray.
Remove your thumb.
In which direction does the warm water move?

Fill the trough with warm water.
Fill the test tube with a mixture of a small amount of ink and very cold water.

Repeat steps 3 and 4 above with one exception: place the test tube just below the surface of the water.
