I got the idea to wet a folded up paper towel put on a butter lid after seeing a commercial cricket water feeder on Ghanns web site, It had a sponge instead. It keeps them from drowning, holds 2-3 days of water, I can pour a little water on it from the chams sprayer bottle in a jam, and toss it when its dirty (about a week). I keep a variety of offerings in there. Fruits, vegies, dry, and the water.
