How to make Backflow Incense Burner

I really like the chinese Jiangnan style architecture, so I made a Chinese style incense burner. I made a special design here, at a specific angle, the roofs of the two pavilions will merge into one, forming a complete fan shape! In addition, incense smoke will flow downwards, forming a state of flowing water! ---------------------------------------------------------------- MATERIALS & TOOLS: Cardboard Aluminum Foil Clay Backflow Incense Cones Model Tree Straw Acrylic Led Switch Wires Acrylic Paint Sponge Hot Glue Gun Soldering Iron
