Two grown men arrested for Drive-By Blowgun Shootings as a prank. Jail time for them?

Not sure about the laws up there, but where I'm from these guys could be charged with a felony. If the weapon could be considered a "deadly" weapon, then they would be charged with shooting from a vehicle or "Drive-by Shooting." If it isn't considered a deadly weapon, then they'll probably get a couple of ault charges which could incur some jail time.
