All Aboard! Hop on The DoSeum Express and travel throughout The DoSeum for a sweet holiday adventure. On December 14th, join us for our Big Day of Play from 10am to 4pm where you can participate in hands-on activities for the whole family. Build a giant gingerbread village, mix your own artisan holiday slime, and create an ornament to take home. Don’t forget to stop by our new exhibit, The DoSeum Express!
