I'm writing a Pirates of the Caribbean fanfic, and I'd like to include a scene where (for reasons I won't go into here) some characters run out of shot for their cannon, and have to use an abundant supply of coconuts as ammo instead.
I'm just not sure how feasible this is.
Would the force of a cannon shatter a coconut? And if the coconut does shatter, would the coconut juice prevent the cannon from being reused right away? I know cannons get cleaned out after every shot, and they do get used on the high seas (where you'd presume there's a lot of moisture), so is cleaning going to be enough to remove the coconut juice? What would happen if the coconut juice is a problem, and you try to fire the next shot anyway?
