Small life and big wisdom: the magical use of tin foil

Magic 1: The small battery becomes larger. The battery air conditioner remote control, portable small electric fan and other items have been put aside for a winter. When the weather is hot, when I want to use it, I find that there is one missing battery. I can’t find a suitable large battery for a while. At this time, the tin foil can be rolled into a ball to fill the gap of the small battery, allowing a small battery to temporarily replace the large battery.

　　

　　 Why?

　　

The metal component of 　　 tin foil is actually aluminum, which has good electrical conductivity. Using it to fill the vacancy of small batteries can turn the circuit from an open circuit into a path, successfully turning a small battery into a large battery.

　　

Magical effect 2: Easy to move large furniture. Large furniture such as sofas at home are difficult to move, especially for some girls who live alone. The movement of furniture is even more troublesome. Even if you use your best to push, it is easy to cause furniture and floors. Damage. At this time, we can cut some tin foil and wrap the four supporting legs of the furniture so that the big furniture can be moved easily.

　　

　　 Why?

　　

　　The surface of the tin foil is smooth and the coefficient of friction is small. When the tin foil is used to cushion the four feet of the furniture, the friction resistance generated during the pulling process is small, and it also avoids the friction between the furniture and the floor directly, which can reduce the damage.

　　

　　 Magical effect three: Silver chopsticks have a strong bactericidal effect to remove black and silver ions. Therefore, people who are able to use silver chopsticks often prefer to use silver chopsticks, but there is a problem. The silver chopsticks at home will always turn black after a period of use. Here to teach you a more effective way to remove silver and black is to use tin foil. Pour some water in a container, add a little salt, and then soak the tin foil and silver tableware in the water. After standing for a period of time, take out the tableware and the tableware becomes as smooth as new.

　　

　　 Why?

　　

The black material on the surface of the silver chopsticks is black silver sulfide or silver oxide generated after the silver element is oxidized. The aluminum metal in the tin foil has strong reducibility. The black silver sulfide can be reduced in the salt NaCl electrolyte. It is a simple substance of silver, successfully removing the black substance on the surface of silver chopsticks.
