2. Just take 2 paper towels, add 2--3 drops of essential oil and essence respectively, fold the paper towels in half and place in the sun, and observe after 2--4 hours. Essential oils are highly volatile and leave no trace on the paper towel, leaving almost no smell or a faint smell on the paper towel (depending on the experiment with the essential oil).
