Rain Chains I think originated from Japan. It's main function is, that it replaces a gutter down pipe. When it rains the water streams down this Rain Chain into a water outlet/drain. They should be made from copper as this gives a peaceful trickling sound. As they are incredibly expensive, I decided to create my own. I will make another one, but out of something like tin buckets or anything metal like. - Drill a hole in the bottom of "bucket" to thread your chain through, and 2 holes on the sides to attach the handles to your bucket. Thread your handle, at intervals through the chain to keep it steady and balanced. At the end of the Rain Chain attach something to catch the water if you are not actually using it as a down pipe.
