[WATCH] How Big Macs Can’t Be ‘Destroyed’

Big Mac

A new video which shows molten copper being poured on a Big Mac is taking the internet by storm. One can see the molten metal bouncing off the burger. This does not mean though that McDonald’s Big Mac is indestructible. This is just a scientific phenomenon known as the ‘Leidenfrost effect’ in action.

The video has intensified opinions against fast food in general and McDonald’s in particular. According to Snopes, many articles have claimed the video to be a proof against the McDonald’s burger. The articles are asking burger lovers to be aware that the Big Mac, which seemed indestructible, might be indigestible too.

According to The Telegraph, the video footage is real. The effect that molten copper has on Big Mac can also be replicated with any other food item with the reason being the Leidenfrost effect. Engineer’s Edge defines it as a phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid’s boiling point, produces an insulating vapour layer keeping that liquid from boiling rapidly.

So what happened was, when the molten metal was poured over the burger, it created a layer of steam with the moisture from the burger. This, in turn, created an insulating layer and protected the food. However, the burger patty did blacken eventually.

According to Engineer’s Edge, the Leidenfrost effect is witnessed regularly by those who cook. For example, many times cooks sprinkle water on a hot pan to gauge its hotness. At that time, the water just skitters across than evaporating quickly because of the Leidenfrost effect.

The video was made by YouTube user Tito4re and has already reached 2,128,433 views as of today. This user has previously filmed himself pouring molten copper on top of many other things and has promised to upload the next video showcasing McDonald’s french fries.
