Make a wing

AsSalyamu `Aleykum wa RahmatuLlahi wa Barakatuh,

Equipment: string, paper (about 15cm x 8cm), sticky tape

1. Fold the paper in half by bringing the two shorter ends together.

2. Pull back one edge of paper by 2.5cm and tape down, so that one surface is longer than the other surface. This is the shape of an aerofoil

3. Thread the piece of string through the folded end and tie the ends of the string together. Turn the aerofoil to the other side.

4. Pull your aerofoil horizontally through the air and watch your wing rise.
