NEW YORK (CBSNewYork) — A video of molten copper being poured over a Big Mac is going viral after the copper appears to roll off and cause minimum damage to the popular fast-food menu item.

The video was uploaded to YouTube last week by user Tito4re and had over 2 million views as of Wednesday evening.

Some viewers jumped to the conclusion that the Big Mac’s reaction, or rather non-reaction, to the copper suggests something alarming about McDonald’s food, but this might not be the case.

The video is an example of the Leidenfrost effect, Snopes reports, which is defined as “a phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid’s boiling point, produces an insulating vapor layer keeping that liquid from boiling rapidly.”

The effect results in an insulating layer that protects the burger and makes it appear as if the copper is bouncing off the Big Mac.

The user has uploaded various videos experimenting with objects and molten copper, including a steak which had the similar reaction of rejecting the damaging effects.
