1. Use friction -- use non-slip pads well:

The anti-skid pad used to pad under the footmat is the best prop, because the anti-skid pad has a good anti-skid function, so it is used to open cans without slipping. Remember, bottle and anti - skid mat should adhere to drab ability useful.

It is recommended to cut the pad to half the size of an A4 file. It is useful for opening cans of various sizes.

Rubber gloves to help:

When you encounter trouble that you can't open, wear your usual rubber gloves for washing dishes. Because of the increase of friction, it is like wearing a Hercules glove, which makes it very easy to open the cover.

Rubber band does not slip:

Take a few rubber bands and wrap them around the jar so that the hand holding the jar won't slip. It will be easier to open the lid. You can even put a rubber band around the edge of the lid to increase friction up and down.

2. Use small things -- one word screwdriver:

Go to the box and find a screwdriver, insert it into the gap on the edge of the lid, and apply force upward according to the direction of the arrow. Because of the lever principle, the lid can be opened slightly easily. At this moment, the screwdriver is also very useful for this kind of ring-pull tin. Use the front end of the screwdriver to pry open the pull ring, so you won't scratch your nails.

Metal spoon:

Tap the cap with the metal spoon in the direction of the bottle, damage the close degree between the cap and the body of the can, let air in, it will be better open. Use the back of the knife is also OK, but pay attention to safety, when there is nothing at hand, you can use the bottle cap against the wall is also useful.

Heating Magic

Hot water towel: twist a cloth or towel with hot water, cover the lid for about 5 minutes, using the principle of heat expansion and cold contraction, so that the tin is good to open.

Direct heating: it is also said that if the can cannot be opened, the lid can be stung close to the boiling water, and the understanding of heat expansion and cold contraction can be used. However, Shandong Huihuang Food Co., Ltd. believes that these methods are a little dangerous, and there may be water vapor running into the can to add the opportunity of metamorphosis, so it is not recommended to use them.
