Hey there! I’m Stella and together with my friend Simon and my talking skunk Stinky, I’m traveling the world to find solutions to single-use plastic. You can learn all about the big plastic problem and the scary plastic soup in our book. Everywhere we go, we challenge children to help us solve the plastic problem. In the UK, Nepal, Germany, Belgium and the Netherlands. Plastic pollution might be everywhere, but so are children. And it is our turn to rewrite the plastic story!

Your teacher can sign up your entire class here, or you can join on your own (ages 8- 12). During this challenge, you will come up with, sketch and build a solution that will influence people’s behaviour when it comes to single-use plastics. Good to know: Stinky and I will help you every step of the way, until you’ve found that planet-saving solution!

Here’s how it works:

1. Go to the Let’s get started page.
2. Sign up.
3. Use the Changemaker toolkit to come up with a cool solution.
4. Upload your solution.

That’s all there is to it, you have now officially entered the challenge! Every solution will be immortalised on this website and shown to the entire online world.

Stinky and I are also selecting a couple of submissions to compete in the Dopper Changemaker Challenge Junior Finals! All finalists will record a video in which they pitch their idea to the jury. The jury will then announce the ultimate winner, who we will help build a prototype of their solution. The prototype will be displayed in a public place for everyone to see!
