The beer bottle cap has a special feature: when pressed, it opens easily, without complicated tools

 There is a small point on the beer bottle cap. Just aim at this point and we can still open the cap simply without having to use an opener.

Aim at this small point, open the beer bottle cap easily

Sealing the lid of a beer bottle creates a pressure difference between the inside and outside of the bottle, making opening difficult.

A method similar to opening a can is to gently tap the bottom of the bottle so that the air at the bottom comes into contact with the top, creating differential pressure to open the lid. However, you should not hit the bottom of the bottle directly, because beer bottles are usually longer and cannot create the same effect as opening a can.

A layer of tight plastic ring wrapped around the beer bottle cap keeps the cap tightly closed. Therefore, one way to open the cap is to use a flame to heat the mouth of the bottle for a few seconds. This will force air into the bottle, and then just gently rotate the cap to open it.

Here are some methods you can use to open beer or other beverage bottles without needing a specialized bottle opener.

Use the key

Use your dominant hand to hold the key, skillfully insert the lock blade under the bottle cap, then turn the key up like you would to turn on a car engine and the bottle cap will pop out. This method is simple but takes time to master, you may need to practice a few times before succeeding.

Use another beer bottle

Place the two ends of the bottle cap upside down or tilt it like gentlemen often do for support, then use your hand to push from the bottom up to pop the bottle cap.

Lighter

Insert the tip of the lighter under the teeth of the bottle cap, then use your dominant hand to firmly hold the beer bottle and pop the cap on.

Use a spoon

Insert the tip of a spoon under the teeth of the bottle cap and pop one edge at a time until the bottle cap can pop off.

Frames

Turn the keyhole in the door frame into a bottle opener, then insert the bottle, the toothed tip of the bottle cap against one edge of the door frame and tilt the bottle so the cap pops off. This is a "weird" way and should only be done at home.
