Method 1:

1. Fill a small zip-keeping bag with one section of water, tie it up with a rope, and then fill it with one section of water. Fill it up one by one, then put it in the refrigerator to freeze. Just break the bag when you use it.

2. Go to the supermarket to buy ice cube bags, which are grids inside the bag. Fill them with water and freeze them. Tear the bag when you use it. The ice cubes will also be in the shape of round blocks.

3. Use a silicone water cup, fill it with cold boiled water, put it in the refrigerator and freeze it into ice. After it becomes ice, it will fall off easily.

Method 2:

Ingredients: 2 cups of pure cold water

1. First, you need to find a mold, which is an ice box, which is sold in supermarkets. Generally, hygienic silicone is used, which is easier to demould;

2. Pour two cups of cold boiled water into the mold, and increase or decrease the water appropriately according to the capacity of the mold. It is recommended to fill the mold fully. It is best to add a support frame under the ice box, place it absolutely horizontally, and effectively prevent the water from cooling rapidly and turning into white ice cubes;

3. Carefully place the mold filled with water into the freezer layer of the refrigerator If there is meat stored in the freezer, it is best to wrap the ice box with plastic wrap or a plastic bag to prevent the ice cubes from being contaminated;

4. Wait for about 1 day, and the ice cubes will be ready. Crystal clear, clean and hygienic.

Some people say that the ice cubes they make are not crystal clear. Why? Use cold boiled water and freeze slowly. Don’t use tap water. Try making transparent ice. Why is it sold in stores? The ice cubes are crystal clear, but the ice cubes made from the family box are white? Let’s explore the reasons why ice cubes turn white and try to make transparent ice cubes using your home refrigerator! What exactly are the white objects? If you use a magnifying glass to look at the white part of the ice cube, you will find that they are tiny bubble particles. These are air bubbles that become trapped in ice when air dissolved in water freezes. Because water will eliminate impure substances other than water during the freezing process, the air dissolved in the water will also become bubbles and be eliminated. But when the freezing process is too fast, the air bubbles do not have time to "escape" and are frozen in the ice cubes, making the ice cubes look white.

How to make transparent ice cubes? ?

1 Generally speaking, there are two reasons why ice cubes turn white: A. The air dissolved in the water turns into bubbles; B. The freezing process is too fast and the bubbles have no time to "escape". . 2 We can start from A and B of 1 and think about ways to make ice cubes transparent. Countermeasure A: Boil the water and try to reduce the air contained in the water. That is, use boiling water. Countermeasure B: The ice cubes sold in stores take more than 24 hours to slowly freeze, which cannot be done in a home refrigerator. However, we can try wrapping cushioning foam around the container to slow down the freezing process. What does the ice cube look like? ?

We made ice cubes using the following three methods: (1) boiling water and wrapping the container with cushioning foam; (2) using boiling water but not cushioning foam; (3) using cushioning foam The container was wrapped in plastic, but unboiled water was used. The results are shown in the figure below: (Left) Ice cubes made using the second method (only boiling water); (Middle) Ice cubes made using the third method (only cushioning foam); (Picture Right) Ice cubes made using method 1 (boiling water buffered foam). It seems that it is too difficult to make completely transparent ice cubes in a home refrigerator, but we still made quite transparent ice cubes. Let me share a secret with you: I heard that the transparent ice cubes with a concave center used in restaurants are made by freezing the ice cubes from the surroundings and pouring out the remaining water before the ice cubes are completely frozen and turn white in the middle.
