Triple Soda Bottle Rocket Launcher Plans
Build your own triple soda bottle rocket launcher from these unique plans.
A must-have project for anyone wanting awesome and cheap backyard entertainment, science project, cub scouts, anyone looking for a new hobby or anyone that loves model rockets but wants an inexpensive alternative to the usual “fire-in-the-hole” engine rockets!
- Makes great gifts for kids!
- Brings out their creativity
- Keeps kids engaged in outdoor activities
- Great for science classes
- Triple Bottle Rocket Launcher lets you launch 1,2, or 3 rockets simultaneously!
- Great for group launchings or contests!
- Our complete DIY Plans show you how to make your rockets shoot as high as possible by using correct fin design.
- You will instantly learn many tips and tricks
- Our launcher contains a special trigger mechanism allowing for high-pressure launches (tested @ 130 psi) without rockets prematurely “leaving” the launcher as like many other launchers.
This launcher is designed for homemade water rockets and is constructed from plastic soda pop bottles. The bottles are one of those rare miracles of serendipity: although designed for something else altogether, they are nearly perfect for making water rockets. Soda Bottles are designed to hold liquids at high pressures, they are very lightweight, and they have a conveniently located ring molded around the neck that’s handy for holding the bottle down while pressurizing it. About the only thing that could make them better is to have the fins and nose cone molded-in for you!
The rockets made from these bottles are surprisingly powerful. A standard 2-liter pop bottle 1/3 full of water, pumped to 80 psi and then released, will eject all its water in less than one-tenth of a second, and at that point (“burnout”) will only be about 2 meters off the ground. Amazingly, its velocity at burnout is around 76 meters per second. That’s over 170 miles per hour! This means the average acceleration during thrust is 111 gs! WOW! Safety rule #1: Never get in the way of one of these rockets…
A plain bottle is of course aerodynamically hopeless, and tumbles fluffily after burnout, rarely going higher than 60 or 70 feet. But if you add fins and nose weight, transforming the bottle into an aerodynamically stable rocket?then all that initial thrust can be transformed into truly amazing altitudes of over 300 feet. You really have to see it to believe it.
You will find that this is a fun activity for anyone to get involved in. Designing and building rockets made out of empty 2-liter bottles allow the creative side in anyone to come out (adults included!). The thrill of having your first “successful” flight keeps you coming back for more. Looking for a new hobby, then you gotta get one of these launchers!
Design, build and shoot rockets made from discarded 1 or 2-liter soda pop bottles HUNDREDS OF FEET INTO THE AIR using water and air from a bike pump or compressor.
Unlike some launchers, this one has?3 launch tubes?which allow for a?slower release of fuel?(water/air) as well as?longer thrust?time giving higher launches. They also give rockets more stability?during initial take-off because it serves as a guide rail as rockets gain speed.
High-quality launcher made out of durable PVC tubing.
No additional expense since the fuel is water and air!?No O-rings?that break and need to be replaced.
Launcher supports air pressures as low as 20 psi and as high as 100 psi. These things really fly high!
For the fun of it, science projects, math projects, school classes, parties, etc. and will almost always draw a crowd of onlookers.
