How to burn incense sticks when you don't have a incense stick holder -- just put it on the toilet, clamping the non-burning end of the stick between the toilet seat and the bowl! Isn't that clever?
The stick burns all the way, dropping ashes into the water as it goes. If anything goes wrong, the burning stick will fall into the water, and go out. And when the stick is finished burning, just lift the seat, and the remainder of the burned stick falls into the toilet. Flush, and you're all cleaned up! Wow!
