1, racket style.
Turn the jar upside down and pat the bottom of the jar with your palm. In this way, because the bottom is hit, the gas dissolved in water is emitted, and then the pressure difference in the tank is affected. The pressure has changed, so it's easy to twist it again.
2. Hot water method.
You can prepare a shallow dish or a wide-mouthed cup, soak the lid in hot water for 1~2 minutes, then dry the water and gently unscrew the lid.
3. Hot towel method.
Soak the hot towel in hot water, and then cover the iron lid of the can with the hot towel. When the temperature of the iron cover rises, you can open the can cover with a towel.
4. Scissors method.
You can prepare a pair of scissors or a slightly larger knife, directly poke the sharp part of the iron cover, let the iron cover leak, and then you can unscrew it.
5. spoon.
You can prepare a stainless steel spoon. Then pry open the edge of the lid with the handle of the spoon. Gently pry open the edge and you can unscrew it.
6. Friction.
The tank cover can certainly be unscrewed, but if the internal and external pressures are caused by the pressure difference, the force can be increased. For example, screw the lid and bottle to a certain depth with two paper towels, then increase the friction force, and then twist it hard and it will open. Tools can be rubber gloves, towels, etc.
