Everyone knows the McDonald's Big Mac consists of two all-beef patties, special sauce, lettuce, cheese, pickles, onions on a sesame seed bun. Ever wonder what would happen if you added piping hot molten copper to the mix?
YouTuber Tito4re posted the video "Molten Copper vs Big Mac" on March 10, and the video continues to trend on Facebook and Twitter, with more than 2 million hits and climbing.
As melted copper is poured over ait almost appears as though the metal liquid bounces off both the sesame seed bun and the burger itself.
Leave it to skeptics' site Snopes to give us the low down on why a Big Mac appears impervious to molten metal.
Apparently, it's all due to something called the Leidenfrost effect, a scientific phenomenon in which a liquid in "near contact with a mass significantly hotter than the liquid's boiling point, produces an insulating vapor layer," according to Engineers Edge.
In this case, the moisture in the Big Mac instantly boiled when it came in close contact with the molten copper, Snopes explained, and the resulting steam created a temporary protective layer. The molten copper hovered over the Big Mac's surface rather than making physical contact.
The same effect happened when YouTuber Backyard Scientist poured molten aluminum onto a raw steak.
The Leidenfrost effect is so fun to watch in action that even the science reality show "MythBusters" tested it in 2009 where host Adam Savage put his hand in molten lead without being burned.
Now is probably a good time to mention that anyone reading this probably shouldn't try any of this at home. That why YouTubers like Tito4re exist, to risk their lives to entertain us with molten metal videos like these.
The next video Tito4re promises to post will be molten copper vs. McDonald's french fries. In the meantime, feast your eyes on this McDonald's Big Mac topped with cheese, lettuce, onions and molten copper.
