The Science Mill in Johnson City will celebrate four years of operation with a new exhibit this month. Aquaponics Greenhouse, a working system that lets visitors discover how fish, plants and microbes work together to create healthy food, opens Feb. 16. Visitors to the 1,000-square-foot exhibit will see vertical growing tubes, living walls of ferns and tanks containing fish, prawns and snapping turtles.
The museum, about a one-and-a-half-hour drive from Austin, opened in 2015 inside a revamped 1880s grist mill and cotton gin. More than 50 playful installations blend art, kinetic technology, augmented reality and computer gaming to expand its visitors’ understanding and appreciation of science.
