Aerofoil experiment

On Wednesday we did an aerofoil experiment.We used all kinds of equipment like blowdrier, straws, paper and string. We had to thread the string through the straws.And once we did that we had to tie the two pieces of string together.Then we had a turn with the blowdrier .We had to go to our desks and draw a  aerofoil and label all the parts then we got to coulor.
