Science Experiments

Its Science Time; In our Science section you can find great experiments to try at home with your family and friends. Science is a great place to discover how things work and react in world around us.

Don’t forget to ask an adult to help you gather all the ingredients that can be found right in your own house laboratory.

 

Tornado in a Bottle

 

Laboratory Equipment :

  • Water
  • A clear plastic bottle with a cap (that won't leak)
  • Glitter
  • Dish washing liquid

Steps:

  1. Fill the plastic bottle with water until it reaches around three quarters full.
  2. Add a few drops of dish washing liquid.
  3. Sprinkle in a few pinches of glitter (this will make your tornado easier to see).
  4. Put the cap on tightly.
  5. Turn the bottle upside down and hold it by the neck. Quickly spin the bottle in a circular motion for a few seconds, stop and look inside to see if you can see a mini tornado forming in the water. You might need to try it a few times before you get it working properly.

The Science behind it:

Spinning the bottle in a circular motion creates a water vortex that looks like a mini tornado. The water is rapidly spinning around the center of the vortex due to centripetal force (an inward force directing an object or fluid such as water towards the center of its circular path). Vortexes found in nature include tornadoes, hurricanes and waterspouts (a tornado that forms over water).
