I’ve enjoyed being the camp science counselor so much! Blast Off Baking Soda Rockets Downloadable directions here Materials I mean how can you not love the anticipation of a good rocket launch? Of all the experiments we did for camp this one elicited the most gasps and excitement. Today’s Arm & Hammer Summer Camp science project will require adult supervision at launch time. I may see it again in December when the tree loses its leaves. The chemical reaction used to launch Blast-Off Bottle Rockets produces enough carbon dioxide to propel the bottle high into the sky! So high that one of the three rockets I made is currently sitting in our persimmon tree 30 feet above ground.

Here you go. There is even a spring made out of a loop of plastic bottle - you can see it just on top of the chute in the image above. The loose end of the rubber band is hooked around the horn of a servo motor, which can then be triggered remotely, or by using a sensor of your choosing. The rubber band wraps around the outside of the chassis, holding those plastic tongues in place. After gluing a cone (the blue thing) to the bottom of the bottle, it receives the parachute and is then slipped over another bottle that makes up the body of the rocket. ![]() The staggered tongues that are left after cutting along this line make up the friction joint. It starts by tracing out a sine-wave-like pattern on the wall of the bottle. The video after the break shows a complete tutorial on how to build one of these. The main portion of the build is made out of plastic soda bottles (2 liter size) to end up with a chamber to store the chute, as well as a friction joint that holds the thing together. It’s an automatic parachute deployment system that you build into the nose-cone of your rocket. This piece of engineering is so simple and elegant, you’ll want to build a pretty serious water rocket just so you can try it out. ![]()
