Idea Lab

Join MOHAI as we tinker, experiment, and create our way through history. Explore in the Idea Lab in the Bezos Center for Innovation or at home using the templates and videos. Activities change regularly!

Explore examples of innovations throughout history, build skills for innovation, and let your imagination soar with activities for the young and young at heart that rotate bi-monthly. At the museum, sit down at the Idea Lab any time for a self-guided, hands-on activity inspired by MOHAI exhibits and programs. Explore the same ideas at home with videos and downloadable instructions for a craft or experiment designed by MOHAI Educators.


Seattle is a city of water – it’s all around us! Learn about boats through Seattle history and about the relationship between a watercraft’s purpose, its shape, and ability to stay afloat. Explore buoyancy further with a design challenge to do at home!
