Introduction: Cigar Tube Humidifier

About: Illegitimi non carborundum.

This compact humidifying element will occupy minimal space in your humidor, allowing you to fill your humidor with more important stuff.

** FINAL STEP UPDATED **

Step 1: Gather Materials

To make your own compact humidifying element, you will need the following:
-- propylene glycol crystals
(I get mine from Cigars International, but other online cigar stores stock them)
-- an empty aluminum cigar tube
-- sandpaper
-- 1/8 " drill bit and drill
-- center punch

Step 2: Strip the Tube

I sanded all of the paint off of the cigar tube for aesthetic purposes, but this step is optional.

Step 3: Prep and Drill

Mark the tube with the punch in 1/4" intervals along a straight line, then drill.

Step 4: Finish and Fill

I squished the rather malleable tube in a couple places while I was handling it, so I used a smaller cigar tube to pop out the dents. After you are satisfied with the tube's condition, fill it with propylene glycol gel.

Step 5: Put It to Use

Cap the tube and set it in your humidor. Admire the vast new space made available to you for cigar storage.

** UPDATE **

After a little more than a month of use, I determined that my humidifier was registering consistently low hygrometer readings, despite rehydrating the gel a few times.

To solve this, I drilled a large number of additional holes (on all sides) to allow for better air circulation and evaporation. It works -- keeps my humidor interior within the requisite 66 - 79% humidity zone.

Below is the finished product.
