5. Present your solution

The best ideas will compete in the Dopper Changemaker Challenge Junior Finals. If you become one of the finalists, we will provide you with the tools to record an awesome video in which you explain why you have come up with the best idea. The jury will then announce the winner, who we will help build a prototype of their solution.
