The best thing about Orphan Black — okay, besides star Tatiana Maslany's incredible performance as seven different people, and the fact that it's awesome — is the tremendous special effects, which allow Maslany to physically interact with her "clones." This video finally explains how this magic is possible!
Okay, admittedly, I've watched the video twice and I still don't understand it, but I think it technically reveals how they're doing it, and the problem is I'm just too stupid to understand it. That said, I'm still fine with calling it magic, because this is clearly science that I've not figured out yet.
