Dark matter is a mysterious substance that we believe exists. We are building amazing detectors to try to find out exactly what it is.

To celebrate Dark Matter Day 2021, we want you to create and artwork in any medium showing something you wish existed!

Perhaps it is a portable lolly-making machine, or a spaceship that can take you to Mars. It can be serious or silly, let your imagination run free.
