Soap bubbles made from solutions containing glycerin will last the longest.
Blowing soap bubbles has always been enjoyable to children. . Bubbles however, usually do not last long and burst easily when they come into contact with another object. Sometimes, they simply dry up. Bubbles are formed because of the surface tension of a liquid. A bubble made with a pure liquid such as water is not stable. Adding soap to water helps to stabilize the bubble.
Bubbles are very light because they are made up of air and a thin layer of fluid that forms a sphere around the pocket of air. They float easily. A slight breeze will be enough to lift the bubble up into the air and cause it to float until it bursts when it collides into another object or when the layer of water on the exterior of the bubble has evaporated.
