Aim: The aim for my wind racer was to use gravity, normal force and friction to help push my wind racer
Method: placing the box on to the base and tying the string and placing the tape to the box and base together and doing the same with the bamboo stick.
Results: It didn’t go as far as I thought it would.

Relevant comment relating to variation in class results.
Out of the whole class I reckon my one was the best because I was the only one who had a different design to everyone else and it had so much potential
