Your whirly bird helicopter will twirl and soar through the air. Learn more about how to make paper helicopters. The helicopter is a classic design that spins rapidly as it descends. It works great when dropped from a high place. Try different amounts of weight on the bottom tab. Notice that the helicopter spins in different directions depending on which direction the rotors are folded.
This video is on how to make a paper helicopter.
How to make:
Don’t Forget: Cut along the solid white lines. Fold in on the dashed black lines (so you can’t see them anymore) and fold away on the dotted gray lines (you’ll still be able to see them along the outside of the creases).
1. Cut Robo-Choppers apart as shown.
2. Take one chopper and cut along solid white lines as shown.
3. Fold down on lines 1 and 2.
4. Fold in along line 3.
5. Fold in along line 4.
6. Fold up along line 5. If you want, tape fold in place.
7. Fold the blades down along lines 6 and 7 as shown.
