How can I make it look like someone is putting a needle in their arm? It's for a student film.
I know this is weird, but in one scene of this film, there is a close-up of someone shooting up heroin. Since we don't actually have the capability (nor desire) to show someone actually doing this, how can we fabricate a device that will look like the needle is being injected in the arm and squirts a little bit of blood out when the needle is removed?
Any advice is greatly appreciated.
