Harry Potter meme - day 05

A bit late today, but better late than never.
I watched Rio - the movie today and I have to admit that I immediately fell in love with Blu. He just reminded me so much of my budgie Dobby [the pet question is still to come, right :D]. Anyway, watch this film and enjoy a colourful journey to Rio :)

So - what is today's question?

Day 5 - What's your wand made of? What's the core.
