In this video, we show you how to make a convection spinner toy so that you can investigate where energy is being wasted in your home. Choose your spinner from

  • Draco the dragon
  • Waldo the worm, or
  • Sneaky the snake.

You can download and print your convection spinner template here.

You will also need:

  • A piece of thread
  • A pair of scissors
  • A needle
  • Some colouring pens or pencils.

We hope you enjoy our workshop!
