Before even thinking about time, make sure eggs do not break Rockets with broken eggs are placed in lower tiers than ones with 2 surviving eggs. Taylor wrote a comment on Coaxial Hotend. An egg survived if it leaves no wet spot on a paper towel. Taylor has added a new log for The Recreator 3D - Make Recycled PET#1 3D Filament.

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. Decorate the rocket in any way you can imagine. ![]() 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. Tape 4 straws to the top of the bottle to be used as legs for the rocket to stand on while launching. 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.
