Back flow incense anyone?

I am a huge fan of incense both in stick form and cones. I

have quite a few sticks of  random scents and over 200 pieces of back flow incense. 

I am really loving my back flow incense and have a huge jar filled with the back flow cones.

I lit 3 here so you can see some good back flow action. Some of the smoke comes out a hole in the bottom of the cone and pools around in the bottom of the cone burner.
