OMG, yes. 4th or 5th grade this was big. I’d go to Hooks and get a jar of cinnamon oil and soak 50 toothpicks with it. I sold them for a nickel apiece to classmates.I remember back in grade school, we would soak toothpicks in cinnamon oil and the longer you let them soak, the hotter they would get. We would literally get "burns" on the edges of our mouths from letting them hang out the sides.
