Heavy Water & Light Ice Experiment. What happens? Ice floating over vegetable oil but it decreases in baby oil.
While the ice melts, water is reduced in both liquids. Implemented gas grows and melt water falls. Then the boundary between the melted water and oil shows a beautiful light effect. It shines like a gold (the principle of internal rejection).
The last session shows a small part of the ice cube, which goes up and down. Of course, you can try this at home.
