Have you ever encountered the problem of being unable to open a can lid in your life? Today I will teach you how to open a can with a plastic lid. Whether it is a tin can or a glass can, you can easily open it.

The first move: "Universal Style".

You only need to find a bowl, and then pour some hot water into it. The hotter the better, preferably boiling water. It is enough to feel that it can cover the bottle cap, and then put the bottle cap downwards. In the water, the water in the basin just covers the can bottle cap. Wait about half a minute to open the bottle cap. Look, it is very easy~

Principle analysis: Why can this method be used to open the can bottle cap? , this is because objects have the characteristics of thermal expansion and contraction. When a metal bottle cap comes into contact with hot water, it expands rapidly. Although the glass bottle mouth will also expand when heated, it is heated a step later and is heated through the bottle cap. In addition, the food inside is cold, so its expansion speed is far slower than the bottle cap. In this way, a gap will be created between them, which can be opened.

The second move: "Breaking Palm Style".

Opening cans relies on fingertips and fingertips. For example, "Powerful Vajra Finger", "Eagle Claw Power", it is said that "Tathagata Palm", "Fire Cloud Palm", "Fire Sun Palm", etc. will also have miraculous effects. However, these exercises are not available in gyms.

Third trick: "Breaking knife style"

Use a knife, scissors or the like to pry open the tinplate edge of the bottle cap to balance the atmospheric pressure inside and outside the can;

Some large condiment bottles are not easy to open even with a bottle opener, which requires a little external force.

Use a stainless steel spoon to gently pry the edge of the bottle cap. When you pry it open a little, gas will enter and the bottle can be opened easily.

The fourth trick: "Broken spoon style"

Use stainless steel, brass spoons, keys (Webster's spoons over 100HV, don't tell you that your home only has ceramic and plastic spoons) , wrap it in paper towels to increase the friction coefficient, pry the bottle cap along the glass edge of the bottle mouth, the can can be opened when air enters, and then use a spoon to dig out the contents inside and eat
