Simple science experiments are perfect to explain to kids how the world around us works in a fun way. These experiments can be made with material we find at home and it won't cost you a dime. In this case we're going to have to light the candle, so if you are doing this experiment with a small child you will have to be careful when lighting it. This experiment basically explains the changes of temperature and pressure, that's why water ascends in the bottle. Don't miss the following experiment to see how the pressure varies when we vary the temperature of a body. Watch this video to learn how to do the candle and water science experiment.

You'll need:

  • Water
  • Glass bottle
  • A candle
  • Fire
  • Colouring


  • If you have to do this experiment with a child, be specially careful when dealing with fire as it could harm him/her.
