This is a magic trick that transposes the water and oil.
You show a tube with a cup pattern and two boxes with water drop and oil drop patterns respectively. Put the water friend in the tube first, then the oil friend. When gently shaking the cup, the water and oil friends mix together, and separate with a snap of your fingers. After removing the cup, the oil will always rise to the top.
【Teaching】Great for kids show and teaching them about water and oil. Why don't water and oil mix? Why does the oil always rises to the top?
