If I get sent back in time unexpectedly. What do I do if I am stranded there?

Tell me simple things that I do to make myself look cool and epic in the eyes of people in the past. Lets say I end up in one of those ancient Mesopotamian cities from 6000 years ago.

Tell me how to build explosives from cow shit
Tell me how to build a blast furnace so i can Cast iron
Tell me how to make steel without advanced technology
Tell me how to build a plane like the Wright brothers did.
Tell me fucking everything that I could possibly be able to do without the need for advanced technology.

also is there a trick on how to learn a language from just listening to people speaking it?

there is nothing there about cow shit bombs.

I wanna know how to make cow shit bombs.

Imagine ancient egyptians fighting their enemies with explosives and canons.

I would sit on a nearby and admire as they conquer the world.

Probably not, but electroplating things is ancient.

They're showing a snake coming out of a lotus. Ancient Egyptians had a lot of mythology and other hieroglyphics of that happening. This one looks similar to a lightbulb by coincidence.

>>6269993
You're probably referring to the Baghdad battery. It's not confirmed it really was a battery, and it's only speculation that it was used for electroplating if it was ever a battery in the first place.

i dont know about explosives from cow shit, but you can make guncotton (the first smokeless modern propellant for bullets) using just nitrogen, hydrogen and cast iron pressure vessels.

first step is making ammonia from atmospheric nitrogen and hydrogen. the hydrogen can be made via steam reforming, and for the nitrogen, just use ordinary air.

http://en.wikipedia.org/wiki/Steam_reforming
http://en.wikipedia.org/wiki/Ammonia
http://en.wikipedia.org/wiki/Haber-Bosch_process

once you have the ammonia, it can be oxidised to make nitrogen dioxide, which dissolves in water to become nitric acid.

http://en.wikipedia.org/wiki/Nitric_acid

once you have the nitric acid, you can make nitrocellulose (a much more powerful alternative to gunpowder)

http://en.wikipedia.org/wiki/Nitrocellulose

as for the blast furnace, all you need is a way of forcing high pressure air into the bottom of a furnace. this can be accomplished with mechanical air pumps, which i'm no expert in. i suggest you look at wikipedia entries regarding the subject

wikipedia covers steel, the principles of flight, and pretty much everything else you would need to know.
