We often eat cans as snacks to supplement nutrition. But I frowned at the thought that the lid of the can was not easy to open. How can I open a can easily and effortlessly? In fact, as long as we master the skills, we can easily open it. Let's introduce you to the tips on how to open glass cans.
1、 Why the bottle cap can't be opened
There are two main reasons why the bottle cannot be opened. One is the pressure difference formed after bottling and cooling. The other is that the bottle cap is fixed on the bottle body, which mostly occurs in carbonated drinks.
2、 Four methods and tricks for opening the lid of canned bottles
First kind
1. Carefully fill the basin with half boiling water; Put the cap part of the can into boiling water for half a minute, and then take it out;
2. Put on insulated gloves, and then lift the bottle cap up with your hand. With no effort, the bottle is opened.
3. Wash and dry your hands with clean water, so that you can remove the sweat or oil on your palms, your palms will not slip, and the rotation resistance will increase.
4. Hold the can cap with your left hand, turn it upside down with the bottom of the bottle facing up, and pat it three times with the palm of your right hand.
5. Then let the mouth of the can bottle face up, fix the bottle body with your right hand, twist the lid with a little force with your left hand, and pop the lid open.
Second
1. First, we choose about 25-30 cm of tape.
2. Then stick the tape on the cap of the can head bottle and stick it counterclockwise (be careful not to stick the glass bottle together).
3. About halfway through, fold the tape in half to make a handle.
4. Then hold the top edge of the glass bottle with your left hand and the handle with your right hand.
5. The can was opened easily.
Third
1. Buy your favorite glass bottles, cans, drinks, etc. Of course, it's for those glass bottled products with metal caps.
2. Find a relatively stable, hard and stress-bearing place, such as the vegetable table, steps or corner ground, and avoid being in an overhead position to prevent damage to ceramic tiles.
3. Stand the glass bottle upside down to ensure that the glass bottle cap can contact the ground or table.
4. Hold the glass bottle firmly and tap the bottle cap according to your strength to let the air in. After tapping, the surface of the bottle cap will drop a little paint. If the bottle cap is often opened, grasp the strength, tap once, and it can be in place.
5. Rotate the bottle cap counterclockwise with your hand. With a little force, you can hear a 'Bang' sound to open the cap, and the cap will be opened. Note: when unscrewing the bottle cap, be careful not to get close to the clothes, so as to prevent the juice in the bottle from splashing on our clothes.
Fourth (most effective)
The bottle cap can't be opened. You can pour some hot water into the basin. The hotter the better, preferably boiled water. I think it's enough without a bottle cap. Now let's start our coup.
1. Specific operation steps: put the bottle cap down into the water. The water in the basin is just over the bottle cap. Wait about half a minute and you can open the bottle cap.
2. Principle: This is because objects have the characteristics of thermal expansion and cold contraction. When the metal bottle cap contacts hot water, it expands rapidly. Although the glass bottle mouth will expand when heated, it is a late step and heated through the bottle cap. In addition, the food inside it is cold, so its expansion speed is far behind the bottle cap. In this way, there will be a gap between them, which can be easily opened. With this method, it will not be difficult to screw the bottle cap in the future. Just soak in hot water. It's very simple.
3. Benefits: when you open the bottle cap in this way, you don't need to pry or bake. You don't have to worry about prying the bottle and hurting your hand, or baking your hand, let alone bursting the bottle. It's very safe! Another advantage of this method is that no matter how big the bottle is, it can be opened easily as long as you head down and soak it in hot water. After practice, this method is the best, almost 100% can be opened.
