You will need:
- candle/tea light candle
- shallow dish

Method:
- Put the candle in the dish and secure it in place by pressing modelling clay/blue tack around its base.
- Then, pour water into the dish around the candle.
- Add a few drops of food colouring (optional). This will help you to see the results more clearly.
