Since we launched our YouTube Channel back in March, many people have written in to ask questions about our Wall of Magic in John Green's salon. So Mangesh and I drove from the New York office all the way to Indianapolis, where art director Danica Johnson gave us the behind-the-scenes tour.

If you have questions about the Wall of Magic that weren't addressed in my lengthy investigative report, leave a comment and we'll drag Danica over here to answer them.
