How would one create a mechanism to increase humidity in an aquarium for a reptile?
This humid air exchanger is a simple design that consists of a plastic canister, a sponge that hangs vertically from the lid, a nipple on the underside of the lid, and two nipples on top of the lid to connect the air hoses (one connects to the air pump and the other obviously would be the humid air output). Had I done some research into the design beforehand, I would have just made one of these myself out of a two liter bottle, old plastic peanut butter jar, etc... A person who has the requisite knowledge and common sense needed to properly take care of a reptile has all of the ability needed to construct one of these according to one's own ingenium. In about 15 minutes or less you could make your own device and save yourself $12 plus shipping in the meantime. Might even be a quick and fun little project to involve the kids with. In the end, yes, this an effective device which could easily be built out of readily available household items.
