Many foods are made of glass jar to pack, such as chilli sauce, beef paste, canned yellow peach and so on, these are delicious things, but in order to extend the shelf life of canned, at the time of canned cans will be pulled out of the air inside, and then hand mechanical arm on the assembly line tighten the lid of the canned, and twist is very tight at this moment.
Every time before eating the can, we should try our best to open the can. Sometimes it hurts so much that we can’t open it. Today, I would like to share with you a few tips to open the can.
One, tap the can upside down, where the lid is, a few times diagonally on the floor. Be sure to hit the edge of the lid, and gently. And then it opens with a little tap, and it works really well.
Method two, the bottom of the can, palm empty, and then beat the bottom of the can, about 5 to 8 times, and then use a rough cloth to cover the lid, the cloth can increase friction, gently twist to open.
Method three, prepare a scissors or kitchen knife and so on under the glass bottle lid, upward gently pry. The reason why it is difficult to open a can of glass bottles is that the air pressure inside the can is much lower than the air pressure outside the can. Prying with scissors can let air in, so that the air pressure inside the can is not different from the air pressure outside the can, so that you can open it with a gentle twist.
Method four, prepare a basin of hot water, and then stand the can upside down in the water, soak 2~3 minutes. The lid of a can can be inflated by the principle of heat expanding and cold contracting. When the time is up, wipe the tin clean with a dry cloth and wring it. It’s easy to open.
Method 5: The main reason why we can’t unscrew the lid of the can is that the friction is not enough. At home, we have rubber gloves, which can be put on the hand and then unscrew the lid of the can, so that it is very easy to open the lid. The friction of rubber gloves is very strong.
