Steps

1.  Pour some water into the clear plastic cup or container.

2.  Add some cooking oil.

3.  Leave this for a few minutes.

After a few minutes the oil will have risen to the top of the cup/container.  The oil becomes lighter than the water.

4.  Put the cup of oil and water into the freezer for a few hours.

Water becomes a solid when it freezes.

The water expands when it freezes and becomes less dense that the oil.

This causes the water to rise to the top.
