Soda Bottle Rocket Launcher

This launcher is a great device for teaching projectile motion (science and mathematics). Each launch is set at a 45 degree angle. Students create rockets out of household materials and test the variables of water amount, air pressure, rocket design, etc. This is also useful for launching water balloons. Users will need a fair amount of space free of people and buildings. Use common sense when launching.

This launcher is designed for homemade water rockets constructed from plastic 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. They're designed to hold liquids at high pressures, they're 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 g's! Yowza! Safety rule number 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 allows 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!
 

     

    Description:

      • Design, build and launch rockets made out of 1 or 2 liter soda pop bottles hundreds of feet using water and air from a bike pump or compressor.
      • High quality launcher made out of durable PVC tubing
      • Unlike some launchers, this one has a launch tube which allows for a slower release of fuel (water/air) and allows for longer "thrust" time.It also gives your rocket more stability during initial take-off.
      • No additional expense since the fuel is water and air! Absolutely NO O-RINGS that break and need replaced.
      • Launcher supports air pressures as high as 100 psi. These things really fly!
      • Adjustable trigger mechanism allows for high pressure launches.
      • Great for fun, gifts, science projects, school classes, parties, etc. and will most likely draw a crowd of onlookers. 
      • Encourages creativity with rocket building out of household materials. The need to build bigger and better rockets is unavoidable for most people.
