Drones aren't particularly easy devices to master -- so you won't want to mess with them too much unless you know the ins and outs.
So here’s a word of advice: Don’t try this at home.
That is, unless you’re as skilled as this drone operator in Montreal who decided to knock a cup off his head with a drone “for no particular reason.”
Watch the precision in the video above as the drone operator -- sitting with complete poise -- flies the potentially dangerous device towards his face.
Spoiler: It's a happy ending.
