What do you think will happen when you roll it across some paper?
Try it and see whether your predictions were correct!

3. Investigate painting different stripes on the roll. Can you picture what will happen when it is rolled across the paper?

You could ask a friend to work out how you painted your roll in order to produce the mark on the paper!
