Ruairi shows off his paper bridge

Brilliant bridges

How do bridges hold up so much weight? Join Ruairi as he conducts an experiment to find the most brilliant bridge!

You can try to build these bridges at home too, you will need a few sheets of A4 paper, some weights to test your bridge (ideally pennies, though items like batteries or teaspoons will work), and a gap to bridge across (we recommend placing two stacks of books a few inches apart).
