Bubbles are formed due to the surface tension of water. This tension is the mutual traction force that exists inside the object and is perpendicular to the contact surface of two adjacent parts when the object is subject to tension. The attraction between water molecules on the water surface is stronger than that between water molecules and air. These water molecules are like being stuck together.

The vibrant summer is coming, which is really the golden season for children to have fun. At this time, I like to take Xiaoxiao to the park often. The venue is large and the air is good. I can also play colorful bubble toys to let children play and chase, which is fun and exercise.
