Fun facts about capillary action:

1. Plants rely on it: Capillary action helps water travel from the roots to the leaves of plants through tiny tubes called xylem, allowing them to survive and grow.

2. Straws work due to capillary action: When you drink from a straw, part of the mechanism is due to capillary action. The liquid rises into the straw because of the adhesive forces between the liquid and the straw’s walls.
