Ingredients:
- 4" PVC cleanout plug
- 4" PVC female cleanout adapter
- 4" PVC cap
- PVC cement
- 1/2" PVC piping (at least 6")
- 3/4'' PVC piping (at least 6")
- 1" screw
- a nut & bolt (just long enough to go through 1/2" PVC)
- CO² cartridges used in airsoft guns
- PVC cutter (is nice but can use a hack saw too) {not pictured}
- Power drill
- 1/8" drill bit
- 3/16" drill bit
- 5/16" drill bit
- 3/4" spade bit
- Baby powder (talcum powder is too hard to find, baby powder is cheap)
Step One: Use PVC cement and bond the 4" PVC female cleanout adapter and 4" PVC cap together. Make it a tight seal. No gap between the two.
Step Two: Cut a 3" piece of 3/4" PVC piping. Drill holes at base where CO2 will escape. I drilled 4 holes with the 5/16" bit.
Step Three: Drill Pilot hole in PVC cap (dead center) and sink in 1" screw. My screw is a hex screw with a rubber gasket. Good tight seal.
Step Four: Use PVC cement and glue 3/4" PVC piping piece dead center inside the 4" Female cleanout adapter/4" Cap thingy with the holes down at bottom closest to PVC cement.
Step Five: 4" PVC cleanout plug needs a hole dead center with the 3/4" spade. This will be for the 1/2" PVC piping to go through. You will need to scrape some PVC out because it won't fit without you helping it. Then with the 5/16" bit drill 8 holes for the powder to escape.
Step Six: Glue 1/2" cap to 1/2" PVC piece (about 3 1/2"). Drill hole for nut and bolt inside mine. This is to prevent the plunger coming out of mine.
Step Seven: Drill hole between cap and mine itself in the plunger. This is for the safety pin. I made my pin from a BudLight bottle cap.
Step Eight: Camoflage your mine as your region ground color matches best. Put Powder in mine, screw tight, bury in ground, pull pin, talk a friend into stepping on it for a test.
