1. Clip a piece of paper (about 15cmx3cm) out of any scrap papers.
NOTE: Harder materials are preferred.
If you don't have scissors, fold the paper and tear it neatly.
2. Bend the paper as shown in the diagram.
3. Secure the two ends of the paper-copter with a paper clip as a weight (wrapping a strip of packing tape would also do).
Hold the lower end and throw it upwards (or drop it from somewhere high up).
The paper-copter spins on the wind.
When I was little, I would play with it on my school rooftop...
Materials: Scrap paper, something as a weight (paper clips, packing tape)
Tool: Your own hand
