What if there is no bubble water in the bubble gun? In fact, in daily life, there are many materials that can be made into water for blowing bubbles. For example, cut up soap and dissolve it in water, or add water with dishwashing essence or shampoo. It has been proved by experiments that the combination of soapy water, dishwashing essence and shampoo with relatively high concentration can make the blown bubbles more durable and not easy to break. Another way is to add a teaspoon of sugar or a little tea to the soapy water and put it in a dark place overnight. You will find that the bubbles blown out by this soapy water are not only bright in color, but also not easy to crack.

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. 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.
