This is a fun activity- when it works. I had to try a couple of times before I was successful. The first orange was too juicy and I wasn’t careful about keeping the inside stem dry. As a result, it wouldn’t light. For my second try, I bought a navel orange and was much more careful when removing the orange pieces. I filled it with oil, as well as adding a few drops of essential oil, making sure to saturate the stem. I waited about 10 minutes before lighting it. This time, it worked at it truly makes a beautiful candle!
