Puzzle animations, programming, and custom item names!

[Bennick]

You know when you have to chisel things in the vanilla story and you'll see the actual hammer and chisel animating to break something? How would I go about doing my own things like that? Also, how does a chemistry type puzzle work scriptingwise? For example, say I want to use a hand drill on Agrippa's head to leak blood into a jar and then have the jar become something new to pick up? How do I make the custom names for all these jars and things? (I assume its lang file related) halpz lol?
