An essential oil burner (air freshener) made from a tin can.
One small tin can (I used a Vienna Sausage can)
Essential oil of your choice
Good scissors, tin snips, or other cutting device
Can opener that opens cans from the side
Step 1: Get a can
Look through the pantry and get the smallest can of whatever. Eat whatever is in the can. Waste not, and all that. Okay, take the label off.
