I'm going to say that's probably real...

You're not going to get a scientific reason from me, just one based on my own stupidity. I often like to feel how hot things are. I've dipped my finger in boiling water before. I've put my hand through a fire. The key is how fast you do it. In the video he does it so fast that even when the footage is slowed down his hand still looks like it never touches the molten metal. In reality it does but it happens so fast that his hand is in the heat for only microseconds and then cools.
