I’ve gotta pull your comment to the main floor.

Phase change is lacking, but conduction, radiation and convection are spot on.

The main issue is that though artistically well done it is a horribly inaccurate description of how an aluminum can decomposes. What made me want to scream while watching the video is when the aluminum can began to rust. Aluminum can’t rust since rust is iron oxide. It can oxidize though (which is grey to black in color not red) and create aluminiun oxide. Also “Aluminium oxide is responsible for metallic aluminium’s resistance to weathering. Metallic aluminium is very reactive with atmospheric oxygen, and a thin passivation layer of alumina quickly forms on any exposed aluminium surface. This layer protects the metal from further oxidation.” (wikipedia)

If he instead used a tin can which is made of steel coated with a layer of tin, then this would be more accurate depiction.

Particularly like the way that the animals constitute completely different sets of character in their respective owners. How can you not read the men with hyenas as being, as you say, alpha-male type domineers and the men with the monkeys being companion-type outsiders?

Can you buy these? Cause I want one and I’m willing to pay $$. Ok, maybe just $.
