What happens if you hang a damp rag along the side of the bator down towards the bottom? and if your worried about it drying, and it will, perhaps so the bottom is in a long rectangle containger of water but you have to add marbles or make it high enough so peeps cant drown... so hard telling you what I "see" lol or maybe if you use more of a handtowel you can leave alot on the outside of the bator and wet it and perhaps the rag will draw the water into the part inside the bator like a wick???? just thinkin to help
