To open the can cap, you can knock the lid several times or pat the bottom of the bottle.

We just need to hold the bottom of the bottle with our hands, then turn the bottle upside down, knock it out on the table a few times, and then twist it with our hands. It is very easy to open the can lid. This method is very easy for children to open it.

Turn the can upside down and hold it in your hand, and then pat the bottom of the bottle hard several times. This should be decided according to your actual situation, and be careful not to use too much force when shooting, so as not to hurt your hand. This will make the air pressure inside the bottle impact the bottle cap, which will make the bottle cap loose, so it will be easier to open. After shooting, let's push a little harder and it will be easy to unscrew.

1. Spoon method

Take out the spoon at home and pry it at the edge of the bottle cap, and you will hear the sound of poof. This is because the unopened bottle is vacuum inside and will firmly absorb the bottle cap, so it is difficult for us to open it. When we deflate, the air pressure inside it is the same as that outside, so it is easy to unscrew the bottle cap.

2. Hot water method

Prepare a small dish, pour a proper amount of hot water into the dish, and then put the can upside down and soak it for half a minute, that is, put the bottle cap in hot water for soaking. When the time is up, let's turn it over first, then dry the water on the surface, and then twist it with a little force by hand to open it very easily.
