Experiment 4

Add some calcium chloride crystals in a test tube, and add a little cotton wool in the top of the test tube, pushing it down with a spatula so that it is just above the crystals. Add a plain nail on top of the cotton wool, and place some more cotton wool in the top of the test tube – label this calcium chloride
