Dry air evaporates more moisture, moist air less. The humidifier covers the bellows intake. I my case I used a 35mm film canister ring with a wick leading into a brass tube water reservoir. This was capped with the top and treads from a plastic bottle attached with a glue gun. The cap and side of cassette was drilled to accept the wick..Window  Screening covers splayed wick on both sides, tacked with glue gun. I am available for personal comment or abuse at bmccall@erols.com.

Use:
-dampen the loose end of the wick and the wick under protective screen
-fill water tube and place water tube over lose end of wick which is attached to the black ring via the white cap
-place ring on air intake of bellows
-after use, empty water tube, recap and store in pipe case as a humidifier.
