I've noticed a lot of people lately asking about using foam, etc. to make waterfall features, backgrounds, and the like. I found this neat instructional article online, and thought I would share! It's for glass enclosures, so would work great for hatchlings (or other reptiles)...or if you have a custom built enclosure with one or more glass walls?
