NEW Version with Adjustable Launch Rail! Soda Bottle Water Rocket Launcher. This is the only one like it on ebay!

Complete Do It Yourself Kit

Launch straight up or go for distance at any angle you desire!

This version has an adjustable launch rail - launch at any angle from 90 degrees to about 15 degrees!

Launcher will enable you to launch a plastic (PET only!) water or soda pop bottle over 250 ft. straight into the air using only water and compressed air from a bicycle pump, a foot pump, or an air compressor. Vertical distance will vary depending on angle, bottle, etc... BUT they will go FAR! The bottles can go way higher/farther with modifications, fins, weight, etc... The fuel (water and air) is essentially free and readily available allowing countless launches without additional expense. Launcher supports air pressure up to 125 PSI. PLEASE READ WARNINGS/DISCLAIMER! After pumping up the bottle to the PSI of your choice, you control when the launch occurs by pulling on the strings to release the trigger from a safe distance and out of the splash zone. Launcher supports 1L, 1.5L 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. Made in the USA by ME from durable non-corrosive Schedule 40 PVC pipe and other parts I get at local hardware stores.

This one is different! It has a ‘spring’ to keep the collar holding the rocket in place during pressurization. Prevents unwanted launches! Also dual string firing mechanism pulls collar straight down instead of to one side, resulting in an instantaneous launch. 'H' design also creates more stability during launch. Launching mechanism is adjustable to accommodate different bottles, just loosen the hose clamp and slide as needed.

This is the COMPLETE do it yourself version. All parts included. The launch rail is prefabricated as is the valve stem, but you will need PVC primer and glue to assemble. Once you glue together, screw launch rail tightly and use two included zip ties to secure pull strings (see pictures). Also refer to pictures to see simple assembly (10 - 15 min.)

Materials and Tools Needed for Launch

  •   Plastic (PET) soda pop bottle. I find that 2L seem to work the best, but I’ve heard San Pelligrino  water bottles work awesome too.

  • ·  water 

  • ·  air source (bicycle pump, foot pump, or air compressor)

  • ·  2 tent pegs, wooden stakes, a wire hanger, rock, or brick to keep launcher from moving when the strings are pulled.

  • ·  Large, open space

WARNINGS/DISCLAIMER!

The seller is not responsible for any injury or property damage resulting from the use or operation of this toy. 

Recommended for ages 8 and up with adult supervision.

Once pressurization has started do not touch or tamper with the bottle in any way.

Do not exceed 125 PSI.

Serious injury can occur - the bottle launches at tremendous speed. DO NOT aim at anyone or anything!

Stand away from bottle when pressurizing.

Only use PET plastic bottles.

If bottle does not launch, carefully remove pump and deflate, then pull off rocket and reseed with less force.
