This holiday season, deck the halls with science! The Science Mill will be open with expanded dates from December 17 to December 31 (closed Dec. 24 + 25 and Jan. 1). Come explore our 50+ interactive exhibits, inside and outdoors, including the newly updated Banana Piano and the return of MindBall—an exhibit powered by YOUR brainwaves! Meet the giant vinegaroon, marbled crayfish and other new animals in the BioLab, and find special pop-up experiences like the Sleigh Racer Challenge and our foot-controlled video game. Deck the Halls Pop-up Activities will run December 26- December 31.

Don’t forget to stop and shop our Science Store for holiday gifts with a science twist—or shop online and we’ll ship anywhere in the U.S. All proceeds support the museum’s STEM programs for Texas youth.

After the Mill closes, enjoy a self-guided driving tour of Johnson City’s Lights Spectacular displays featuring 2 million twinkling holiday lights (Nov. 27 through January 3; 6pm-midnight).

Sleigh Racer Challenge (December 26-December 31)

Using recycled materials, engineer a super-speedy sleigh for dashing through the snow (or the Hill Country). Test your design on our racing route. Will you set a new record or get stuck in park?

Step into a Video Game (December 26- December 31)

Jump, stomp and tap your way through a video game adventure where your feet control the action! Play solo or team up; either way, this game will keep you on your toes.
