I mean I could figure out how to buy a drone online (is it really that cheap?).
Yes. Drones are very cheap. Only the capability scales with cost. But in general drones are incredibly cheap compared to their capability.
Then I think I need to get a drone license to fly 'em around as practice
You do not need a license to practice flying drones. Neither the FCC nor FAA are going to come arrest you during the hour your battery lasts. Just don’t go fly over an airport or government building. You’ll be fine.
But I’d have no idea how to make the C4 nail-bomb or where to get the stuff for it.
Good. Keep it that way. I am absolutely not going to tell you, or anyone else, how to make explosives or weapons.
