Many of the hooks we use in daily life are suction cup hooks, which do not leave adhesive marks on the walls. Moreover, if they stick well, the suction force is very large. But when many people stick this type of hook, they just stick it to the wall and then buckle it off. In fact, before sticking the hook, they need to simply handle it to make it firmly stick to the wall. The method is very simple, we only need to use a little egg white. Usually, there is some egg white left in the leftover eggshells we eat. We use our fingers to evenly apply the egg white on the eggshells onto the suction cup of the hook, and put it aside first.

Next, we will wipe the wall where the hook is to be attached with toilet paper to remove any dust from the wall, and then apply a little egg white to the area where the hook is to be attached.

Next, simply stick the hook coated with egg white to the wall and let it stand for more than ten minutes, waiting for the egg white to solidify and dry.

After the egg white dries, we can hang something on the hook. At this point, we can see that the hook is very firmly attached, and even hanging objects weighing more than ten pounds is no problem.

This is because egg white is a gelatinous substance that can reduce the gap between the suction cup of the hook and the wall. This creates a vacuum between the suction cup and the wall, and our hook can firmly adhere to the wall. If the hook often falls off, or if you need to stick the hook the next time, you can also try this method to ensure that the hook is firmly attached.
