Method for making bubble water - Physical analysis and precautions
Method for making bubble water
Method 1: 2 cups, 1 bag of tea, sugar, boiling water, detergent.
1. Take a cup and pour boiling water, put it in a bag of tea;
2. Add 1-2 spoons of sugar to an empty cup, pour some detergent, pour in tea, and stir with chopsticks;
The bubble water is ready, and the bubbles blown out with this bubble water are large and not easy to break.
Method 2
1. Cut the soap into small slices and place it in a cup, pour hot water and dissolve the soap slices.
2. Add an appropriate amount of sugar and bags of tea to the cup, cover the lid and leave it overnight.
3. Everything is OK, the hygienic and environmentally friendly super bubble liquid is ready, and the effect is very ideal.
Method 3
Soaking water recipe: 1 cup of water + 1/3 cup dish soap + half a spoon of sugar, stir. The bubble water made in this way will not have a pungent smell, and it will be safe.
Method 4
You can use dishwashing detergent and a little vinegar. As long as the dishwashing detergent is sufficient, the effect is indeed good.
Method 5
Glue: Water: Detergent: Hand sanitizer (shampoo) == 1:4:2:2, you can also add sugar to increase the effect and add blue ink. The bubbles with pearlescent hand sanitizer or shampoo are better in color, and the bubbles will not break easily if added with sugar and vinegar.
Method 6
Materials: 2 parts detergent, 6 parts water and 1 to 4 parts glycerol.
Method to slow down the disappearance of bubbles: Water evaporates very quickly. When water evaporates, the bubbles disappear as soon as the surface of the bubble breaks. Therefore, some substances must be added to the bubble solution to prevent the evaporation of water. This water-receiving substance is called hygroscopic substance. Glycerin is a hygroscopic liquid that forms a weaker chemical bond with water, which slows the evaporation rate of water.
Method 7
Ingredients: soap, hot water, color ink (add color)
Mix a portion of liquid soap, 1 portion of glycerin, and 6 portions of water to make bubble water. In daily life, there are many materials that can be used for blowing water, such as chopping the soap and dissolve it in water, or adding water to dishwashing or shampoo. It has been proved through experiments that adding three solutions of soapy water, dish soap and shampoo with comparable concentrations can make the blown bubbles last longer and not easily break. Another method is: add a teaspoon of sugar or a little tea to the soapy water and put it in the dark overnight. You will find that the bubbles blown out of this soapy water are not only bright in color, but also less likely to burst. Physical analysis and precautions for bubble water
Causes of colorful bubbles: When light passes through the film of soap bubbles, refraction will occur on the top and bottom of the film, and the soap film can contain up to about 150 different levels.
The messy color combination we see is caused by an unbalanced film layer. The last film layer reflects red light, the thinnest reflects purple light, and the center reflects colorful light. Reasons for the formation of
bubbles:
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 surfaces of two adjacent parts when it is subjected to tension. The mutual attraction between water molecules on the water surface is stronger than the attraction between water molecules and air. These water molecules are like being stuck to a beggar. But if water molecules are overly bonded to one lu, bubbles will not easily form. Soap “ breaks ” reduces the surface tension to only 1/3 of the usual conditions, and this is the best tension required for blowing bubbles.
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 surface of the bubble breaks. Therefore, some substances must be added to the bubble solution to prevent the evaporation of water. This water-receiving substance is called hygroscopic substance. Glycerin is a hygroscopic liquid that forms a weaker chemical bond with water, which slows the evaporation rate of water.
Notes:
1. Soaking water is one of the important toys for children. When buying soaking water, you should pay special attention to the safety of the soaking water solution.
2. There are so many soaked water manufacturers on the market, but there are very few people who are truly safe in the formula. The alkaline ingredients in the bubble aqueous solution can corrode children's skin, and fragrances have many unsafe factors. Therefore, when buying soaked water, parents must not be greedy for cheap things, and should buy brands with good reputation.
