How to make bubble water – physical analysis and precautions of bubble water

there are many bubble water manufacturers in the market, but the real formula safety is rare. The basic ingredients in the bubble water solution will corrode the skin of children. There are many insecurity factors in flavors.


making method of bubble water – physical analysis and precautions of bubble water

making method of bubble water

method 1

materials: 2 cups, 1 bag of tea bag, sugar, boiling water, detergent.

1. Take a cup, pour boiling water into it, and put it into the tea bag;

2. Add 1-2 tbsp sugar into the empty cup, pour in some detergent, pour in tea, and stir with chopsticks;

bubble water is made. The bubbles blown by this kind of bubble water are big and not easy to break.

method 2

1. Cut the soap into small slices and put it in a cup. Pour in hot water to dissolve the soap.

2, then add the right amount of sugar and bags of tea into the cup, cover and place overnight.

3, everything is OK, and the super bubble liquid of sanitation and environmental protection is made, the effect is very ideal. Method 3:

formula of bubble water: 1 cup water + 1 / 3 cup detergent + half a spoonful of sugar, stir. The bubble water made in this way will not have a pungent smell, and it is safe.

method 4

can use detergent and a little vinegar, as long as the concentration of detergent is enough, the effect is really good.

method 5

glue: water: detergent: hand washing liquid (shampoo) = = 1:4:2:2, you can also add sugar, increase the effect, add blue ink. The color of bubbles is better with pearlescent hand sanitizer or shampoo. Bubbles are not easy to break with sugar and vinegar. Materials: 2 parts detergent, 6 parts water and 1 ~ 4 parts glycerin.

method to slow down the disappearance of bubbles: the evaporation of water is very fast. When the water evaporates, the bubbles disappear as soon as the bubble surface breaks. Therefore, some substances must be added into the bubble solution to prevent the evaporation of water. This kind of material with water collecting property is called hygroscopic substance. Glycerol is a kind of hygroscopic liquid, which forms a weak chemical bond with water, thus slowing down the evaporation rate of water.

method 7

materials: soap, hot water, color ink (add color)

mix one part of liquid soap, one part of glycerin and six parts of water together to make bubble water. In daily life, there are many materials that can be used for bubble water, such as cutting soap into water, or adding water with dishwasher essence or shampoo. It has been proved by experiments that the combination of soapy water, dishwashing powder and shampoo can make the bubbles lasting and not easy to break. Another method is: add a small spoonful of sugar or a little tea into the soapy water, and put it in the dark overnight. You will find that the color of the bubbles blown out by the soapy water is not only bright, but also less likely to break. Physical analysis and precautions of

bubble water

bubble colorful reason:

when light passes through the film of soap bubble, the top and bottom of the film will produce refraction, the soap film can contain about 150 different layers at most.

the messy color combination we see is caused by unbalanced film layers. The last film layer reflects red light, the thinnest one reflects purple light, and the middle one reflects colorful light.

bubble formation reason:

bubble is formed due to the surface tension of water. This kind of tension is the mutual traction force existing in the interior of an object and perpendicular to the contact surface of two adjacent parts when the object is under the action of tensile force. The attraction between water molecules on the water surface is stronger than that between water molecules and air. It’s like these water molecules are stuck together. But if the water molecules are excessively bonded to each other, bubbles are not easy to form. Soap & lt; Break & quot; It reduces the surface tension of water to only 1 / 3 of that under normal conditions, which is the best tension for blowing bubbles.

methods to slow down the disappearance of bubbles:

the evaporation of water is very fast. When the water evaporates, the bubble will disappear as soon as the bubble surface is broken. Therefore, some substances must be added into the bubble solution to prevent the evaporation of water. This kind of material with water collecting property is called hygroscopic substance. Glycerol is a kind of hygroscopic liquid, which forms a weak chemical bond with water, thus slowing down the evaporation rate of water.

precautions: 6667

1, bubble water is one of the important toys for children. When buying bubble water, you should pay special attention to the safety of bubble water solution.

2. There are many manufacturers of bubble water in the market, but few of them are really safe. The basic ingredients in the bubble water solution will corrode the skin of children. There are many insecurity factors in flavors. So when parents buy bubble water, they must not be greedy for cheap, they should buy brands with good reputation.
