fly your helicopter

Make your helicopter

To fly your helicopter, hold the top of the propeller and bottom of the craft stick near the paper clip.

2.

Twist the propeller until the rubber bands are entirely coiled. Then, keep twisting until you can’t twist anymore. Your rubber bands should be at least triple coiled!

Make your helicopter

3.

Hold the helicopter vertically and release the helicopter in two short counts. On the first count, let go of the propeller. On the second count, let go of the paper clip. Your helicopter should fly!

Troubleshooting Tips

Make your helicopter

Paper clip not staying?

Use more masking tape and wrap the tape around the paperclip multiple times while pressing the tape firmly against the popsicle stick!

Make your helicopter

Helicopter not flying?

Coil your rubber band even more! Make sure you release the top of the helicopter FIRST and then the bottom about half a second later!

How it works

Make your helicopter

1.

Energy is stored in the coiled rubber bands of the helicopter.

2.

When flown, the rubber band rapidly releases its energy by unwinding, which turns both the propeller blade.

3.

As the propeller spins rapidly, it begins to push air downward. The helicopter is then able to fly in whatever direction it is pointing.
