You can't smell metal


You can't smell metal

Pick up a shirt!

Metal has no odor and you can't smell it. But what are we smelling then?

It turns out that it's mostly a chemical called 1-octen-3-one, which is generated when your skin oils react with metal that you've touched.

I thought this was really interesting, and I decided to try making pure 1-octen-3-one myself and to see what it smelled like.

I Can't Taste Anything

Adrian Wellock lost his sense of taste. After suffering a cold, he started getting a metallic taste in his mouth, which took his palate with it. These days, he only eats foods that are simple to chew and adds spice and herbs to ratchet up the smell. Find out what it's like when everything, actually tastes like nothing.

All about Mercury, the Liquid Metal | Element Series

In this video, I'll be talking about the very interesting element Mercury. I try to cover as much as I can, including its properties, its history and interesting reactions.

Let me know what other element you would like to see. Keep in mind that this takes a lot of work though, and that not all elements will be possible (due to rarity and/or danger).

Let me know if I forgot anything in the description. I probably left out links or something.

Thrown into the deepest darkest cavern
The place where your torment triumph
The other rotting corpses where like their master
Their betrayed hearts were turned to death

Rotten to the core, rotten to the core
Rotten to the core, corpses rotten to the core

But now see them, maggots infested
See them their throats are like the tombs
Their betrayed hearts were turned to death
And now you can see the result

Infernal process of eternal suffering
The ground strewed by dismembered corpses

Now ear the scream of the grave
The smell of putrefied flesh
You can't do anything for them
You have to choose your way

Be sure no man is able to break the curse
The process of imminent death is merciless

Confront your demons
To feel the true essence of power

Rotten to the core, rotten to the core
Rotten to the core, corpses rotten to the core
