Not a bad idea! Love the thought of doing a leidenfrost effect for a video (Since I love sciencey stuff too) I think the intro and outro are nice but you could always possibly tinker with adding a nice soft background music. Also, maybe throw in some animations. It doesn't have to be fancy, just some text maybe or a picture if you're feeling creative but, since it's a more sciencey video, you wouldn't need to get too fancy, I'd imagine. That and if you can somehow get a nice zoom in of the actual leidenfrost effect, that would have been awesome! Keep it up though man! I think this channel could really do well.
