However, if the water molecules are excessively bonded together, bubbles are not easy to form. Soap "breaks" the surface tension of water. It reduces the surface tension to only 1/3 of that under normal conditions. After the bubble is formed, a large surface tension is required to make the bubble bigger.

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.
