Can I use chopsticks for diffusers?

If the chopsticks are porous and non-coated wood ones you can place them in a jar or vase and add diffuser oil to use them the same way as a reed diffuser. A jar or vase with a smaller opening at the top would be better because it would keep the diffuser oil from evaporating as quickly.

Great question! I am actually not sure. Some of the diffuser sticks I have are wood, so maybe the wooden bbq skewers might work. I would certainly give one set a trial run to find out. Here is a site to help out.

I wood use bamboo ones or kebab sticks. Try and experiment before giving to others.
