After inserting it, use the lever principle to hold the back half of the screwdriver, press it toward the bottle cap, and knock a little gap out to let air in.

After the air enters, the Laoganma bottle cap can be easily opened.

As long as you hear the popping sound, it means that the air has poured in.

In addition to this method, there is a little trick.

With this little trick, even a weak woman can easily do it.

The specific operation method is to form a 45-degree angle between the bottle body of Lao Ganma and the ground. The mouth of the bottle should be above the ground. Knock the edge of the bottle cap hard a few times, and then twist it easily and it will be OK.
