I’d give laser pointers to Neanderthals. Even if they did figure out some useful application for them (maybe hunting?) they’d run out of batteries eventually.
A cube of pure tungsten. So when they pick it up they cant believe how heavy it is.
After further consideration, I would also give them a Solar-Powered TV that plays nothing but a Video of Hatsune Miku doing Fortnite Dances
To fuck with? Contraceptives, obviously!
rip
A copy of Windows Vista
Sharpies. Think off all the confused scientist that have to explain sharpie marks under acient paintings.
A coke bottle
Drop it from an airplane. Bet they would then say among themselves:
God Must Be Crazy!
Slinky
Let’s give some ancient peoples a couple books on modern maths and calculus. Really fuck with the development of tech.
Fuck yeah, just give the ancient Greeks hindu-arabic numerals and watch them lose their minds. Teach Zeno calculus and watch him try to prove it wrong.
Pretty sure the greeks knew about the hindu number system, they were neighbours for centuries. They just thought zero was of the devil and geometry was better that algebra and never adopted it.
Those little Roman devices nobody can figure out.
Antikythera mechanism?
That’s Greek and we have a pretty good understanding of them.
I think the person you’re replying to is referring to these odd little dodecahedrons that we keep finding in former Roman provinces, but for which we’ve found no documentation as to what they were for, if anything.
No, those little dice things nobody can figure out at all. They’re octagonal with a little ball on each corner.
It’s how the Greeks played Minecraft.
Go to that greek dude who invented the steam engine and give him the idea to make a train
Humanity - civilised Greeks or not - didn’t have the metallurgical knowledge to be able to build locomotives and rails out of strong enough materials yet. Ancient Greece basically coincides with the Bronze age.
You’d have to not only bring (knowledge of) steam locomotive tech, but also every single bit of iron tech required to build one. You could skip the requirement for rails by opting for a steam traction engine, not a full locomotive, but those are far closer together in technological ability.
None of this factors in the propensity for steam boilers to explode, which you may or may not consider important.
There’s a reason we were still using beasts of burden (horses, oxen, etc.) for traction until the 19th century.
Advanced maths and physics textbooks
Furbies. Just to see if we end up with a furby based religion.
Meth
Nuclear bombs.
That would fuck with them so hard.
Toothpaste. Try making that out of saltpeter and bronze!
