Jonathan, or YouTube user "carsandwater", enjoys watching how different objects interact with super-heated nickel, and his videos are getting anywhere from 2 million to 9 million views. The one pictured is floral foam, and the reaction is pretty incredible. You can watch that video here, but he also has several other clips gaining millions of views.
You can see his YouTube channel with all of the clips here. Just don't try this at home.
