Mimi’s Rainbow Adventure: the exhibition in London

The exhibition is now closed but the information is for reference.

The London exhibition

Mimi has lots of questions; about the sky, the sea and everything in-between! One summer, when Mimi is staying with her granny, they go off on an adventure, with Colin the dog and Dave the robot, to meet lots of inspiring scientists to help her finally get some answers to her big questions.

Experience this new story as it comes to life at the IOP’s new family-friendly exhibition: Mimi’s Rainbow Adventure.

Get hands-on with fun physics experiments for all the family, be creative with arts and crafts activities, read an inspiring book in our chill-out corner and find out how physicists can answer your big questions about the world. Have your own rainbow adventure this summer with a season of free activities for all to enjoy.
