In life, sometimes you encounter a situation where you struggle to open a tightly twisted plastic or glass bottle cap, despite your best efforts. Quantrimang.com has compiled tips for opening tightly twisted plastic/glass bottle caps, so please refer to them.
Increase friction
For tightly twisted glass or plastic bottles, find a rough piece of fabric and place it under your palm, then tightly wrap the bottle cap to increase friction and twist it again. The bottle cap will open.
In addition to rough fabric, you can also use other available objects such as a dry towel, a silicon pad, a rubber band, rubber gloves… to increase friction and easily open bottle caps.
Tap the cap
Use a spoon, a sharp knife, or any hard object to lightly tap the cap in a circular motion along the edge, then twist gently, and the cap will open immediately.
Use heat
Use a hairdryer to blow hot air around the cap, pour hot water onto the bottle, jar, or turn the bottle, jar upside down and soak the cap in hot water… These are effective ways to use high temperature to open tightly twisted caps. Remember to use fabric or a pad and then twist the cap to avoid burning your hand.
Hit the cap
For bottles, jars, or cans with stuck or tightly twisted caps, if tapping the cap does not work, hold the unopened container upside down and hit the edge of the cap on the ground with a thick piece of fabric several times. If you hear a “pop” sound, then you can open this stubborn cap.
Use a hard object to open the cap
For metal bottle caps, especially those used for food storage, the air pressure inside is much lower than the outside air pressure, making it difficult to open. In this case, you can use a gentle stainless steel spoon to pry the edge of the bottle cap to allow air to enter, equalizing the inside and outside air pressure. This will make it easier to open the bottle cap.
Tap the bottom of the bottle or jar
You just need to invert the bottle that cannot be twisted and leave it for a while. Finally, gently tap the bottom of the bottle with your hand to reduce the air pressure inside the bottle. When you hear a small sound, you can easily open the cap.
