This is probably one of the strangest experiments you will ever see on YouTube. First of all, it is actually dangerous if you’re not an expert. This involves a molten copper that can burn you really, really bad. In this clip, a molten copper was poured on a crystal ball. I bet that you were thinking that the crystal will explode, actually, the ball handles molten copper. It is really fascinating to watch, but don’t try this if you’re not an expert. Watch this clip.
