Johnson City: Deck the Halls with Science

December 17, 2020 (All day) to December 31, 2020 (All day)

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). Explore 50+ interactive exhibits, inside and outdoors, including the new Remarkable Reflectors whip, newly updated Banana Piano and the return of MindBall—an exhibit powered by YOUR brainwaves! From Dec. 26-31, find special pop-up experiences like the Sleigh Racer Challenge and a foot-controlled video game.

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).
