About

The Science Mill in Johnson City, TX is a must-see for the whole family!

The exquisitely redesigned building has modern aspects that make this modern learning center a little industrial, a little rustic and oh boy!

Scientists Bonnie and Bob, a husband and wife team, built the Science Mill themselves. They enthusiastically share this was one of the best and craziest adventures they helped launch. Bob compared himself as a co-pilot to his wife's idea, and together they allowed the Science Mill to take off, figuratively speaking.

Upon arrival, you’ll be given a QR Code while a friendly docent will assist you in making a robot avatar. The QR Code allows you to open up a world of interactive discovery at each station. If your trip coincides schoolchildren on excursions filling the Science Mill, you’ll appreciate how they run from interaction to interaction with unbridled energy and enthusiasm.

Tour the Science Mill with your QR code to discover the mysteries of science - from cell phone waves, silos and much more!

In addition to the many indoor exhibits, head outdoors to explore other amazing exhibits such as the spurred African tortoises.

When planning a trip to the Science Mill, plan to take a half day to enjoy all its offerings. Pack a lunch or snacks and enjoy taking a break in the designated areas of Science & Art Park.

The Science Mill is a vibrant destination if you are looking for a fun place for the whole family or a unique experience for yourself.

Science Mill: Fun facts and Cool features

For many, one of the favorite activities at the Science Mill is the hands-on exhibit called Deep Sea Robotics. It is like combining a video game with interacting with the legendary marine explorer Jacques Cousteau! Use the handheld controller for the underwater drone and watch a screen to monitor how it rose through the water.

This exhibit features a 6,000 gallon tank complete with terrain modeled after the Mariana Trench and Challenger Deep.

Another notable exhibit is the aquaponics greenhouse, which is a mouthful! In simple terms, aquaponics combines raising fish (aqua) and growing plants in water (hydroponics). The ecosystem depends on the fish releasing nitrites and nitrates from their waste, feeding the various plants. At the 1,000-square-foot facility, you’ll spot tilapia, shrimp, and koi whose waste fed the fruits and plants that grew in tubes.

One fascinating historical fact is that Lyndon B. Johnson carved his signature into one of the walls at the Science Mill - authenticated and hidden in one of the offices of the building.
