how to make a smoking pipe out of a light bulb

Just let the gas in and flow out through alternate hole that is similarly sealed as a one way valve. Hooking up a bottle of the carbonated water to the jar with vinyl tubing would be easy enough. Another great source of pure CO2 is club soda. and then seal the hole where the 'J' tube comes out of the jar lid. Just let the dry ice sublimate completely. This valve is very similar or exactly like a beer or wine making bubble air lock valve. I would probably use a small bubble cup valve since no real pressure is involved. It is easily available and you don't need any other devices. The dry ice method seems the most practical for filling the jar with CO2.

I have not tried this yet, but plan to soon. Do not seal the jar with dry ice still inside because it will continue to sublime and creative positive pressure which may become a safety hazard. After the dry ice has completely sublimed close and seal the vents. Without heating first, place a small piece of dry ice in the jar and let it sublime into CO2 which will displace the air. They are often filled with flammable gases such as propane and if you use one you will be creating a bomb, not a light bulb.ĮDIT: As suggested by many in the comments, dry ice could be used as an alternative to a CO2 canister. It is meant to be an air duster, however regular canister air dusters will not work. I got mine a few years ago at Office Depot. Note: This is the only step that requires an unusual tool, the air nozzle. Tighten both acorn nuts to ensure a good seal. Remove the air nozzle from the vent and quickly screw an acorn nut onto it. While continuing to blow CO2 into the jar, screw an acorn nut onto the open vent. The cold CO2 should fill the jar while the hot oxygen-containing air will be forced out of the second vent. Use your air nozzle to blow CO2 into the jar via one of the vents. Remove the jar from the oven and place on the table.

This step should be completed quickly so it may be worthwhile to practice.
