Materials:
- 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.
