When you have built some vehicles you can test them to see how they perform. You could compare the vehicles you have made against each other, or you could test your vehicles against some that your friends have designed and made. The competition can be held between individuals or with small teams working on different vehicles.

Find a large open space to hold your Vehicle Olympics. For a water event you will need to find a bath or body of water, such as a small pond, that you can hold the race on. You should make sure that an adult is present if you are using an open body of water, as this can be dangerous.
