One soda bottle water rocket launcher prefabricated parts kit with adjustable trigger mechanism, launch pad, and instructions for assembly and launching. Launcher ships completely unassembled with easy to follow instructions. Launcher will enable you to propel a 2 liter plastic (PET) soda pop bottle over 350 ft. into the sky using only water and compressed air from a bicycle pump, a foot pump for a car, or an air compressor for tools and painting. Fuel (water and air) is essentially free and readily available allowing countless launches without additional expense. Launcher supports air pressures as low as 20 PSI up to 120 PSI. You will be amazed how high only 40 PSI will propel a bottle with fins attached to it. After pumping up the bottle to the PSI of your choice, you control when the launch occurs by pulling on the brightly colored string to release the trigger from a safe distance and out of the splash zone. Launcher supports most .5L, 1L, 1.25L and 2 liter plastic (PET) bottles. Great item for people of all ages for fun, science projects, school classes, parties, etc. and may well draw a crowd where it is used. Trigger mechanism slides up or down by loosening the hose clamp to accommodate variations in bottle construction. Made in the USA from durable non-corrosive Schedule 40 PVC pipe. NO additional expensive materials are required such a wooden board for base, metal mounting brackets, or expensive pulley for string to operate the trigger. Materials and Tools Needed for Assembly: PVC cement, duct tape, scissors, ruler or yardstick, tape measure (optional), flat blade screwdriver (or 5/16 in. or 8 mm socket wrench). Materials and Tools Needed for Launch: Plastic (PET) soda pop bottle, water, air source (bicycle pump, foot pump, or air compressor), 2 tent pegs (wooden stakes, wire hanger, rock, or brick) to keep launcher from moving when the string is pulled.

Good for personal not classroom use
I bought this kit with the hope of using it as my new classroom water-rocket launcher, but found that it has to be adjusted depending on the type of bottle students use, so it's a no go for this purpose. Attempts to use it on a variety of bottle types without adjustment resulted in repeated mis-launches while pressurizing (6 in a row with one student's bottle). I would say that the materials are good--just remember you'll need to buy PVC primer and cement--thus my 4-star rating, and it works like a charm once assembled for the specific bottle you intend to use.

Every physics classroom should try this.
Worked great for my classes, but the holding mechanism started to slip after a few trials.

It is great. We had one kinda like this at a Cub Scout Day Camp and I wanted one for use with my group. The instructions and parts were easy to follow and assemble. It works great! I am very happy with it and glad that I got it.

great fun
The only issue I had was getting the ring that held the 2 litter bottle down to stay around the neck of the bottle. Once I figured out to hold the ring up and pump 2 or 3 times until it had pressure in the bottle we had a great time.

My students loved putting the launcher together. It was the hit of the STEAMM event at school.
