As in, a Time Traveler Essentials T-Shirt.
Yeah, right. It doesn’t mention once either black powder or alcohol. Look: it’s great to bring up nuclear fission and everything, but those two inventions combined will fuel any number of gunpowder empires
Sheesh. Maybe they thought that potential owners had already memorized the relevant bits anyway.
I hate that shirt and that poster. It’s too focused on book learning, when it’s the *engineer* time travellers that will prosper.
I know why they didn’t put gunpowder on in. They didn’t want an idiot sueing them after they blew their hand off. As for alcohol, most cultures in history know how to do that.
