How to make a paper helicopter

Cut a strip of paper 20 cm in length and 3 cm wide.

Copy the design shown in the diagram on the left.

Cut along the solid line between A and B and cut the two little slits above C and D. (Do not cut the dotted lines - they show folds.)

Fold up the bottom flap (underneath C and D) and press it flat against the helicopter's "body".

Fold flap C over until it lies flat on top of the centre part of the helicopter's "body".

Turn the paper over.

Fold flap D over until it lies flat on top of the centre part of the helicopter's "body".

Hold flaps C and D in place with a paperclip.

Fold helicopter blade A towards you and fold helicopter blade B away from you.

Your helicopter is ready to fly!
