Due to "scattering", a large number of microparticles scatter the light several times, so that it appears white with light blue. Experimental verification: Take a glass of water, place it on a dark background, put a drop of milk in it, then use a flashlight to illuminate one end of the cup and approach it. The light from the flashlight will appear clear. blue in the water. If you put more milk in the water, the whiter the water becomes, because light is scattered over and over again by these many milk particles, and the result is white.
There is a cup that changes color when you put water in it, and a picture appears inside. What is this cup called and what is its principle?
Because some studies have shown that a comparative chemical analysis of overnight water samples and tap water samples after being left for one, two and three days found that the pH, phosphate, nitrate, dissolved oxygen, chlorine and chemical oxygen consumption values are within the normal range. In other words, water at night has no side effects on the human body and can be drunk.
Functional form
Water cups are the containers we use to hold liquids every day. They are usually shaped like a cylinder with a height greater than the width, so they can be easily used. taken by hand and maintains the temperature of the liquid. There are also square water cups and other shapes. Some water cups oAlso have handles, handles or additional functional structures such as anti-scalding and heat preservation.
Water cups are usually small and can be easily picked up with one hand. The bottom of the cup is wide and can be placed stably on the table. The body of the water cup is made of solid, water-insoluble materials such as glass, ceramic, plastic and metal, and can safely hold a variety of edible liquids (such as water , drinks, wine, etc.).
This type of mug is called heat sensitive color changing mug. It is composed of an outer cup and an inner cup arranged coaxially. There is a heat sensitive cup between the bottom. ends of the two cups. The color-changing volatile liquid interlayer cavity is engraved with an artistic graphic channel that communicateswith the cavity on the outer wall of the inner cup. After pouring hot water into the drinking cup, the heat-sensitive liquid in the interlayer cavity will change color and rise into the graphic channel of the inner cup, causing artistic patterns to appear on the wall of the cup. cup, allowing people to gain aesthetic feeling and artistic enjoyment. .
Since the heat-sensitive liquid is in the inner layer of the cup, it will not come into contact with the beverage in the cup and will not cause contamination. Since it is a confined space, the volatile liquid cannot escape and can be used an unlimited number of times.
