Gasoline Powered Soda Bottle Rocket Launcher. Designed & Tested By C.L.Raub

Step 26 Fire !

Firing instructions

1. Make sure there is no bottle on the launcher.

2. Fill the gas tank by turning it up side down putting the filling hose in gas and pumping the
primer bulb until all the air is out of the line and gas starts to run out of the copper tube.

3. Make sure you don't have a bottle on the launcher.

4. Run the air pump to expel any excess gas from the vaporizer assembly.

5. Now you can put the bottle on the launch tube and press down until it hits the stopper.

6. Press the primer bulb 1/2 pump you should see the fuel run into the vaporizer tubes.

7. Turn the compressor on and pressurize the bottle
to 25-35 psi.

8. Any higher is at your own risk.

9. Fire!!!

10. Repeat 4-7

11. IF it does not fire, don't get in front of the
launcher. Wait a few minutes, then unscrew the launch
tube and remove and replace the bottle
(the bottle may be flooded)

Try putting a few ounces of water in the bottle, this will give you a nice boost.

You can also shoot this from the hip if you feel confident enough after a few firings,
I don't however advise shooting from your shoulder unless you devise some facial
Shielding, or other protection.
