Unique experiments with Gallium - special metals that can melt on human hands

Gallium is a special chemical element, it is metal but so soft that it can melt even when placed on human hands.

According to Wikipedia, at temperatures greater than 29.76 degrees Celsius (above room temperature but below the human body temperature of 37 degrees Celsius), Gallium is a liquid. So when you put this metal on human hands, it will melt. At ambient temperatures, the metal is silver-green but in a liquid state it looks like white silver and mirrors.

Because of such strange properties, Gallium is often used in many studies. Recently, Dan and Gav guys of YouTube channel Slow Mo Guys have experimented with Gallium and slowed down their very interesting movements.

The two men performed liquid Gallium slowdown in three different scenarios. First, they poured Gallium liquid onto the speaker to see its reaction to vibrations.

In the second experiment, they poured Gallium out of a large cup into the plate below to create an effect that looked like a full-river river.

The image slowed down the Gallium pouring from a large glass and falling Gallium drops.

In the final test, the Dan and Gav guys decided to pour Gallium onto the empty surface to see how it would move when something hit.

For details about how those scenes are, you can see the entire slow Gallium test of Slow Mo Guys in the video titled "Pouring a Liquid Mirror in Slow Motion", roughly translated as "Close-up process of liquid mirroring when turning slowly "below:
