Step 2Add the candle: Place the tea candle in the dish and carefully light it.
Step 3Prep the jar: Lightly spray the inside of the mason jar with perfume (or rubbing alcohol).
Step 4Cover the candle: Place the jar upside down over the candle.
Step 5Observe: Watch as the flame goes out and the colored water rises up into the jar.
