Hóuzi needs to get some bananas from the tree at the top of the hill to his house at the bottom of the hill. We used our knowledge of friction to build a sled that would help Hóuzi transport his bananas, our sleds had to go slow enough to ensure the bananas didn't fall off. Check out our building and testing in action.
Our favourite design was the sled with wood wrapped in cardboard, the cardboard created just the right amount of friction to slow the sled down .
