How to make a quick easy air lock:
Items needed:
1 large pill bottle with lid or spice bottle or any plastic bottle (spice or beef bullion bottles work)
1 small pill bottle that will fit into the large bottle
1 Bic ink pen or any rigid plastic tube about 4 to 6 inches long
Water proof glue
Hand drill or wood burner
1 large and one small drill bit ( make sure the large bit is a little bigger then the barrel of the pen)

Steps:
1. Remove guts from the pen.
2. Drill a hole with the large bit in the bottom of the large pill bottle
go slow on this step so you don't crack the bottle.
3. Drill 3 or 4 holes with the small bit into the lid of the large bottle for vents, this lid is the dust cover (these holes can be made with the wood burner but its real smelly).

4. Put the pen barrel about half way in to the large hole and glue in place. Put a small dab of glue in the small
hole in the side of the pen barrel to seal it. Let the glue dry.

5. Put it together - Hold the pen barrel and put the small pill bottle upside down on to the pen barrel inside the large bottle.

Well that's it just add enough water to fill about half way, put on the drilled dust cover, and put into any bottle in a cork or rubber grommet.
A couple quick things to note: Make sure that the inner pill bottle does not touch the bottom of the large bottle, but rest on the tube.

If it does then just cut it off a bit.

Hope this helps
