D&T Lesson Idea: Origami Windmill


  • 1x Skewer
  • 1x Straw
  • 1x A4 piece of paper
  • 300mm of sticky tape.
  • Some type of box

So the challenge is to build a wind powered device that lifts a pencil/pen the height of a desk. The fan is placed 500mm away with 3 speed settings. Ideally you want your design to work on the lowest fan speed. Sounds easy, but that’s because you’ve already seen my solution.
