The metal that melts in your hands (without risks to your health)

There are hard metals, there are very dense ones (such as osmium, which is twice as dense as lead), and there are also very soft ones (such as cesium, which can be cut with an anointing knife).

Metals that fuse at very low temperaturesWe have mercury, which is toxic, and also gallium, which can be handled safely.

Metal to spend jokes

He gallium (Ga) melts at 29.76º, that is, It can become liquid only with the heat of your hands.

These properties make it an ideal ingredient for chemists to play jokes, such as serving a cup of tea with a teaspoon of gallium that will disappear on contact with the liquid.

The name of this strange element comes from the Latin Gallia, with which France was named in ancient times. However, in its etymological origin the Latin term is also present: gallus, a translation of Lecoq that literally means "rooster", the name of the first man of science who recognized gallium as a chemical element. French chemist Paul-Émile Lecoq de Boisbaudran, discovered the gallium spectroscopically in 1875.

It is a chemical element that does not exist free in nature, which is created artificially (it emerges as a byproduct in the manufacture of aluminum). Its applications focus on semiconductor technologies and as a component of some alloys with low melting points.

Gallium is an element found in the body, but in very small quantities. For example, in a person with a mass of 70 kilos, there are 0.7 milligrams of gallium in his body. If this amount of gallium were condensed in a cube, the cube would only measure 0.49 millimeters on its side.

Apart from gallium and mercury, there are two other metals that can be kept in liquid form at room temperature: cesium and rubidium.

In return, the tungsten It has the highest boiling point, with 5700 ° C and also the highest melting point of all metals, with 3,422. Its high heat resistance makes it very useful for industrial applications such as drills and ovens.
