A4 paper, pencil, ruler, scissors, pencil /colours and a drinking straw
Mark the A4 piece of paper with a pencil after measuring in along the short side
approx 40mm. and cut.
You will then have a strip of paper 40mm x 300mm. Follow the link here to see how
to fold and cut the paper so that you can race them with others. You can use coloured
paper as I did and design and colour to you own liking.
