Hi! Rocketeers,
I have made this at home and have had a lot of FUN launching a water and air pressurized 2 Liter soda pop bottle.
The Original idea came from our 1999 Family Reunion, that was the first time I had seen one of these.
I use the bottle over and over.
Click on the small picture to see a larger picture. Each Picture will open in a new window, for reference.

This is about the right amount of water, the bottle is about ± 1/3 full.
You can adjust the amount to get the maximum height of the rocket.
Sounds like this.

Parts List:

6 FT. of 3/4" PVC Plastic Pipe, 200 PSI Minimum Burst Pressure

Cut the 3/4 " pipe to the following lengths:

3 pieces each 4" long, (2 are the legs at the valve stem end and 1 is the upright for the launch end).

4 pieces 2" long (2 are for connecting the "T"s at the launch end & stem end and the other 2 are for making the bottle rocket nozzle).

1 piece 5" long (this is the upright on the valve stem end).

1 Piece 32" long (this is the long connector between the valve stem end and the launch end).

2 Pieces 7 ½ long (These are the legs at the Launch end that connect to the "T").

Additional Parts needed:

5 each, 3/4 PVC Pipe end caps (one cap for each of the 4 legs and the last one is to be drilled to pull the Tubeless valve stem into before this cap is cemented into place on the stem end). Drill a 9/16" hole in the center of the PVC cap, deburr the hole edges and pull the Tubeless valve stem into the cap before the cap is cemented into place. Note: wet the valve stem with liquid soap to ease pulling the valve stem into the hole.

4 each, 3/4 PVC Pipe "T"s

2 each, 3/4 PVC Pipe Couplings (one is to be used for the rocket launch stand and the other is to be cut into 3 pieces so as to remove the ridge in the center of the coupling).

1 each, Tubeless Valve Stem Note: Pull the Tubeless valve stem into the cap before the cap is cemented into place on the stem end upright piece).

1 small can of PVC Cement.

Assemble Parts to look like this, and Hey! A picture is worth a 1000 words. ;-)

I made 2 Cuts on one of the 3/4 Couplings so as to remove just the center 1/4" (there is a ridge inside the center of the Coupling). This gave me 2 short couplings 1" long each.

Remove some material from the threads on the bottle neck to get the Coupling piece to fit on the threads of the neck. When I got this to fit on the threads remove and Cement liberally the coupling to the bottle and one of the short 1" pipe pieces into the cut Coupling.

Mine looked like this . I had the other short Coupling and short piece of pipe to make another nozzle for a second rocket.

I gave the Cement some time to Cure to the bottle .... I know! I know, you can't wait!

I attached my Tire pump to the Tubeless Valve Stem.

I Filled the Bottle (Rocket) about 1/3 full or about 4" of water.

Quickly turn the Bottle Rocket over and slip nozzle into the 3/4" Launch Coupling.

Pump the Tire Pump ... Pump .... Pump ..... Did I forget to Cement any joints? YEP! .. Cement Joints.. Pump ... and more pumps ..... Don't try to pull the Rocket off ... if anything is wrong and the Rocket won't Launch Remove the Tire pump and release the pressure by Depressing the valve stem pin before getting near or touching the pressurized Bottle Rocket.

If all is well What Daffy has to say about the Launch !!!!!!!

Good Luck!!

BTW, the Green Bottle Rockets are the hardest to find...
