1, with lighter: using the principle of thermal expansion and cold contraction, you can aim at the beer bottle cap with a lighter and light it around. Then turn the beer bottle upside down and pat the bottom of the beer bottle with your hand. Then twist the beer bottle cap by hand, and then you will find that the beer bottle cap can be easily unscrewed.
2. Use chopsticks: you can find chopsticks, aim the chopstick head at the bottom of the beer bottle cap, grab the bottom of the bottle mouth with the other hand, then hold the chopsticks tightly and tilt them upward to open them.
3. Use hard paper: If you have hard paper at home, you can fold it into a very small and hard square. Then aim at the bottom of the bottle cap and pry it up, you can easily pry the beer bottle cap open, and the paper is usually something at home, which is easier to find.
4. Two bottles of beer: If you have two bottles of beer, you can put one bottle of beer on the table, stick the lid of the other bottle on the first bottle, and then hold the two bottles and tap them lightly, which is faster than the bottle opener and effortless.
5. Use a spoon: The bigger the spoon, the better. Put the small head of the spoon under the bottle cap, put your hand on the bottleneck and suddenly exert yourself. It's like using a lighter, but it's much simpler and faster.
