-An elephant trunk of hot water-

Purpose: To know which kind of water has less relative density: hot or cold water.

Materials:

1. Two empty similar bottles.

2. A sheet of wax paper.

3. Hot water.

4. Cold water.

5. Red ink (or any colour).

Steps:

- First, put some of the red ink in one of the bottles.

- Then, fill the same bottle with hot water to its orifice.

- After that, fill the other bottle with cold water and cover its orifice by a sheet of wax paper.

- Next, put the bottle with cold water up-side down on the orifice of the other bottle which contains the ink.

- Finally, drag the wax paper gently from between the two bottles.

- Pay attention not to spill any water while doing the last step.

Conclusion: The hot water goes up in the bottle of the cold water as an elephant trunk. What we conclude from this experience is that the hot water is lighter than cold water. This means the relative density of hot water is less than the relative density of cold water.
