As an update I am close to my final assembly and I am so satisfied with the way the waterfall came out. I will outline the crafting process in the final post, but the changes I would like to make are the spout in which the incense is held. Without really thinking I noticed that the handle of a gallon milk jug is the perfect size to drop the incense in so I hot melt glued it to the top of a bottle. The issue is, after burning the incense for a couple minutes the plastic started to melt and the nice incense smell mixed with a gross chemical scent. I am still unsure how I am going to resolve the issue, but I have a couple more glass bottles that when smashed may create a feature perfect for what I need.
