Why are the two bowls sucked together? How can the big bowl and the small bowl be seperated when they sucked together?

Stacked bowls sometimes suck together. The reason for this may be that the water in the bowls is not poured out after washing the bowls. After a long time, the air in the two bowls is squeezed out, forming a vacuum and causing the suction together; or because The bowl is hot, and when the other bowl is placed on top of it, the air is isolated. As the temperature in the bowl decreases, it will expand with heat and contract with cold, causing them to suck together. In this case, it can be solved by soaking it in water, boiling it, putting it in the refrigerator, gently bumping it on the table, and wiping it with cooking oil. Let's take a look at how the big bowl and the small bowl can be separated when they are sucked together.

Why do the bowls suck together？

Bowls are necessary daily eating utensils. The bowls at home are usually placed in the cabinet. Sometimes two bowls are attracted together, especially when the large bowl and the small bowl are stacked. What is going on? Generally, two bowls are sucked together for two main reasons:

1. After washing the bowls, if the water in the middle of the two bowls is not clean, if they are placed together for a long time, the layer of air inside may be squeezed out, and a vacuum will be formed between the two bowls, resulting in suction Therefore, after washing the dishes, you must empty the water inside, not only to prevent the dishes from being washed together, but also to avoid the breeding of bacteria.

2. Another reason why the bowls and bowls suck is that one of the bowls was very hot at that time. When the other bowl was buckled, the air inside was isolated from the outside air. As time went by, the inside of the bowl The temperature of the air in the room gradually decreases, the heat expands and the cold contracts, and the air pressure inside decreases, so the outside atmospheric pressure presses the two bowls tightly together.

How can the big bowl and the small bowl be separated when they are sucked together?

When we wash the dishes, sometimes the bowls will be sucked due to the moisture in the gap between the bowls, especially if the small bowls are placed in a large bowl, sometimes they are sucked together as if they are stuck, and they cannot be beaten at all. Open, so what if the big bowl and the small bowl get stuck together?

1. We can soak it in water first, the water level should cover the height of two bowls, then pour some dish soap and turn the bowl over, heat it for a while and then scald it with boiling water. If there is a gap between the two bowls, use running water to rush against the gap. Generally, the large bowl and the small bowl can be separated in a while by doing this.

2. We can also put the sucked bowl in the pot and boil it for a while, and let it cool naturally. Sometimes the bowl will come off by itself during the cooking process; then put it in the refrigerator for half an hour , Take it out and insert the tip of a knife into the gap between the bowls to gently pry it off, be careful not to scratch your hands.

3. You can also pick up the big bowl that is stuck to the small bowl, and gently bump it on the table (pay attention to the strength of knocking on the bowl, don't damage the surface of the bowl). Repeat several times to get rid of it.

4. Another method is to pour a little edible oil into the gap between the two bowls, and then shake the bowl to let the oil lubricate the part that is sucked. After the lubricating effect, the bowl can also fall off easily .
