Johnson City: Rocket Day!

July 3, 2016 - 12:00pm to 5:00pm

Kick off your Fourth of July with Rocket Day at the Science Mill! Have you ever thought about what makes rockets blast off? Create your own fuel concoction to shoot Fizzy Bottle Rockets, or engineer simple rubber bands to propel your String Rocket Racer the fastest. Check out more power with our explosive Hydrogen Ball Launcher! Or, see if you can get a hole-in-one on our special Foam Rocket Golf Course. Then, let off some steam in our 3D theater with special showings of Legends of Flight to continue your aviation adventure, or perhaps scale down from large fliers to small fliers with Bugs! A Rainforest Adventure. These events will rock(et) your world!
