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.

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.
