Imagine for a moment, that you have an evil historical figure who has committed like a bonch of genocides and then you invent a time machine, go back in time and you have to punish him some how in some cruel way that doesnt destroy the space time continuum.
So you reach into your pocket and you pull out a chocolate bar, and an idea dons on you! Tyrant: "What is that?" Scientist dude: "Its a special treat, have a taste." Tyrant takes the smooth package feeling the softness of the interior as the scientist rubs his hands together maniacally. Tyrant: "This... is... food?" Scientist: *nods furiously* "Its a... uh... special treat sire." The Tyrants opens the smooth package and sees a brown milky substance almost reminding him of the interior of a pastry, he puts it to his lips and takes a bite.
There was a long moment as the tyrant paused, the scientist waited hopeful.
Tyrant explodes with emotion: "This is incredible, what is it?"
Scientist: "It is Chocolate, and now it will not exist for another 3000 years."
And that kids is how alchemy was born.
