The moment you hold gallium in your hand, It becomes smooth and glides through your fingers as if it were a liquid. It only leaves a sticky feeling and small stains.

Although gallium has the power to nearly destroy many substances, How can it be explained that it does not harm the human body?

Here liquid gallium was left on the computer We see. Molten gallium shatters the computer after a certain amount of time.

In the previous video it was gallium that could tear the computer apart, here it is It never harms the hand.

So how does this situation arise?

In fact, gallium causes metals such as aluminum and steel to melt. chemical reaction caused by entry. Just as water rusts iron but does not harm our hands, an accelerated version of a similar situation applies to the interaction of these elements (gallium, aluminum).

When this element combines with aluminum, it forms an alloy called amalgam. This alloy seeps into and dissolves the atomic crystal structure of aluminum, making it brittle. Solid aluminum can therefore be easily broken down in combination with gallium and gallium It causes structural damage to the substance it interacts with.

The surprising thing is that if gallium wants to achieve this, It requires very little intervention. Even placing a very small amount of gallium on aluminum and steel is enough to cause the alloy to form.

Silver-colored gallium has a very low melting point of 29.4℃. It alloys readily with most metals and can even be used as a component in low melting point alloys.

This element melts and liquefies quite easily, but it requires very high temperatures to cook. It expands when frozen and is only one of the few substances that can do this.

In addition, it is found that the alloy obtained by the combination of metals such as gold, nickel and copper with gallium hardens at mouth temperature, and this alloy is It is used as a filling material in dentistry.

Playing or handling gallium, a 100% metal, poses no danger. In addition, the toxicity of the compounds contained in this element is quite mild, but they should obviously not be inhaled or ingested.

In summary, gallium takes liquid form in our hands, but it damages several metals. It is the result of a chemical reaction with metals. For example, if we come into contact with water and salt separately, nothing happens, but when these two compounds come together, the salt dissolves in the water.

Well, gallium is for you too. Does it remind you of the movie Terminator 2?
