HERE'S HOW
Is water sticky? Try this to find out. On a smooth plastic surface, pour out a puddle of water. Set an undented plan firmly in the puddle, making sure it is completely wet underneath. Now pull straight up on the pan. It will be hard to pull up. Be carfeul not to pull up too hard, as you may injure yourself.
WHY?
A principle called adhesion (add-HEE-zhun) makes water act "sticky" like adhesive tape. Adhesion is the property of attraction between two different substances.
