What's the trick if the big plastic bucket lid can't be opened?

Sometimes we are worried because the plastic bottle cap can't be opened, and angry because we don't have the strength to open the bottle cap. Let's see how to open the lid of a big plastic bucket.

First, pour some hot water into the basin. Of course, the hotter the pot, the better the effect. It is best to only boil water. I think we can get through the bottle cap, and then we can use our coup below.

Put the bottle cap down into the water and see that the water in the basin has just passed the bottle cap. Wait about half a minute, and you can open the bottle cap. Isn't it amazing? Anhui Hanwang Plastic will tell you why this method can open the bottle cap. In fact, this is because objects have the characteristics of thermal expansion and cold contraction. Metal bottle caps will expand rapidly as soon as they come into contact with hot water. Although the glass bottle mouth will expand when heated, this is a later step, which is heated by the bottle cap.

And because the food inside is cold, its expansion speed can't keep up with the bottle cap. So there will be a gap between them, which can be pulled apart. Look, it opens easily. With this method, it is no longer difficult to screw the bottle cap in the future.

Just soak it in hot water. It's simple. In this way, there is no need to pry, bake, worry about breaking bottles and hurting hands, worry about baking hands, worry about glass bottles bursting and plastic bottles collapsing. Very practical and safe! Another advantage of this method is that no matter how big the bottle is, it can be easily opened as long as the head is dipped in hot water.
