Firstly Mrs McLean got two clean stramboli jars the same size.
She filled one up with cold water, and the other jar with hot water.
Secondly she put two drops of orange dye in the hot water so the two will look different.
Next she put a piece of cardboard on top of the cold water.
Then she tipped the jar over and put it on top of the other jar
so the hot water is on the bottom and the cold on the top.
Penultimately the hot water started to swap places with the cold water
so they were now the same colour as the hot.
Finally the hot water and the cold had mixed.
This experiment shows us that the hot water molecules mix much better than cold water molecules.
also the hot water rises because hot water is lighter than cold water.
