I found some plastic condiment cups at Wal-Mart. They fit in my humidors perfectly. Before I got my beads, I was having a lot of trouble with my puck humidifiers...they seemed to humidify based on the position of the moon or something. Anyway, I took them out and put distilled water in these cups. The humidity stabalized and slowly increased until it got to about 67%. At this point I took out the cups and it slowly went down to about 64%. While a slight pain, this teeter-totter humidifying technique was better than the wild results I was getting with my pucks. I was putting the 50/50 solution in them every time and I think I ruined them perhaps.

The beads make everything easy.
