2023 Hot Selling Bubble Guns Toy for Kids 8 Holes Outdoor Games Party Bubble Gun

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.

After filtering the tea leaves with the hot tea water, add some white granulated sugar, mix it well, drop some detergent, and then let it cool down. After half a day, blow it again. The safe formula is non-toxic and harmless, and the proportion is moderate. This water is very good for blowing bubbles, because white granulated sugar can increase the tension of bubbles, so bubbles can be blown very large, and the stimulation to babies will be smaller.
