I watched this like 12 times, I can't figure the trick out. Is it mirrors??

I bet it's wires - look at that tall black structure on the other side of the fence.

"Every magic trick consists of three acts.
The first one is called The Pledge. The magician shows you something ordinary, but of course, it probably isn’t.
The second act is called the Turn. The magician makes his ordinary something do something extraordinary.
Now, if you’re looking for the secret... you won’t find it.
That’s why there’s a third act, called The Prestige. This is the part with the twists and turns, where lives hang in the balance, and you see something shocking you’ve never seen before."
