Gallium: it melts in your hand but it attacks other metals

gallium-melting-metal

This might be one of the rarest elements on earth. Galium is a metal with an ultra low melting point of just 29.76 °C and the ability to attack most of the other metals by diffusing into their metal lattice greatly and weakening their structure.

In 1871, the existence of gallium was first predicted by Russian chemist Dmitri Mendeleev, who named it “eka-aluminium” on the basis of its position in the periodic table. He also predicted several properties of the element, which correspond closely to real gallium properties, such as density, melting point, oxide character and bonding in chloride.

Elemental gallium is not found in nature, but it is easily obtained by smelting. Very pure gallium metal has a brilliant silvery color and its solid metal fractures like glass. Gallium easily alloys with many metals, and is used in small quantities as a plutonium-gallium alloy in the plutonium cores of nuclear bombs, to help stabilize the plutonium crystal structure.

This is the coolest thing that I have seen in my whole life. It makes me feel like I’m Magneto, controlling the metal properties. I’m really shocked by it. You should really check it out.

Spider sent into another dimension

So this video is one of the coolest things I’ve seen in a while. It’s about this spider that falls on this guy2s computer, so he decides to use a YouTube video to send it into another dimension.

That’s actually really clever. I would not be the way I handle things when I see a spider. If I were that guy, I would just scream and throw my computer away to kill the spider.

But I have to say I actually feel bad for the spider. What if you were just walking around and then suddenly you are in a tunnel with a lot of colors and shapes?

Check out the full video in case you’re interested. I hope you enjoy it much as I did.
