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.

There are manual bubble guns and automatic bubble guns. The manual bubble gun is driven by pulling the trigger by hand, while the fully automatic bubble gun is driven by the motor to drive the tooth wheel. There are two movable wheels on the top of the last tooth wheel. The movable wheel is divided into two sides to squeeze the hose next to it, mainly by squeezing the hose section by section, and then the water can be pumped up to blow out a long string of bubbles.
