1. Pry with a knife point. If the glass bottle cap cannot be opened, we can first use scissors, or some knife tips to gently pry the glass bottle cap, allowing outside air to enter the bottle. This allows easy opening of the glass bottle cap. The principle of this is to keep the atmospheric pressure inside and outside the can balanced, thereby easily prying the bottle cap.
2. Clap with your hands. First, we need to form an arch with our palms and fingers together, then turn the bottle over and pat it vigorously upward for 5 to 10 times. The principle of this is to cause the air on the top of the can to vibrate upside down in the canned liquid, causing small bubbles near the sealing rubber to rupture, causing local density to increase in a short period of time. Naturally, we can open it with a gentle twist.
3. Use hot water. First, we need to add a little hot water to the basin. Just submerge the glass bottle cap with hot water. At this time, it is necessary to put the lid of the glass bottle downward in the water for 30 seconds, and then forcefully open the lid. This principle is because all objects have the principle of thermal expansion. The bottle cap expands rapidly when contacted with hot water, and the bottle mouth also expands. During the expansion process, cracks are created, and air enters, allowing the natural bottle cap to open.
