When you place a straw through a liquid, adhesion causes the liquid molecules to cling to the sides of the straw. This interaction creates a meniscus, allowing the liquid to rise slightly within the straw due to capillary action. This phenomenon occurs because the adhesive forces between the liquid molecules and the straw material are stronger than the cohesive forces between the liquid molecules themselves.
