Tornadoes are dangerous, deadly, and also hard to explain to kids. In this weather experiment, we’ll talk about how tornadoes are formed which will hopefully make them seem a little less scary to the little ones.

SUPPLIES YOU’LL NEED:

  • 2 two-liter bottles
  • Tape
  • Washer
  • Food coloring (optional)

STEPS TO TAKE:

  1. Fill your first bottle 3/4ths the way full
  2. Feel free to add food coloring or glitter which will make your tornado easier to see
  3. Add the washer to the top of the first bottle
  4. Add the washer to the top of the first bottle
  5. Tape the two bottles together. (Make sure you do it well so there are no leaks.)
  6. Flip the bottle upside now and give it a spin

EXPLANATION:
Similar to a tornado, the water moves in a circular motion which is called the centripetal force. It’s then pulled down creating a vortex. This connects the storm cloud to the earth’s surface to make a tornado.
