Step 1: Parts
-piezo (lighters off bbq's)
-texter or pen (connectoer pens work best)
-tape (i used making tape, it works better)
-1 inch pvc pipe
-lynx deodourant ( or a cheap copy )
Step 2: Putting Together or Construction
2. Then cut away the thread and rib of the bottles ( where the lid screws on, include the whole thread and rib).
3. In one of the lids, cut a hole just big enough fo the pen to push into(with force).
4. Glue the pen into the lid
5. Once that dries, glue the bottle threads inside the pipe. ( u may need to file the rib at the end of the thread, so that it will fit into the pipe).
6. Now make sure the lids screw on
7. drill two holes in the pipe, and screw in the ...screws. check that they are about half a cm from touching each other inside. because the spark from the piezo has to jump across the screws to ignite the gas.
8. screw the cables from your piezo to the screws on the pipe
Step 3: Aim..... Fire!
1. push the end of the pen into a potato, then make sure the potato is pushed down further into the pen.
2. unscrew the lid on the opposing side
3. get some deodourant, body spray type works better than powder.
4. spray some deodourant inside the pipe, when spraying- hold can 6inches away from pipe ( this makes sure the gas, oxygen and the liquid are put inside) trust me, u need all three.
5. put the cap back on quickly, aim and fire by pushing the button on your piezo.
-- my one shoots about 25 meters, depending on what type of deodourant is used. (some work better than others)
