A few years ago, we wrote about what would happen to a McDonald's cheeseburger dunked into hydrochloric acid. YouTube channel Let's Melt This decided to conduct a similar, but different, experiment to see what would happen if you poured sulfuric acid on a McDonald's Big Mac.

Unlike the previous news video, this one's an up-close look with a time lapse so you can see exactly what happens to the burger while the acid works its magic. The half hour process is sped up into a two minute time lapse.

Notice how hydrochloric acid will turn a cheeseburger into a black goo, while sulfuric acid will cook a Big Mac from the outside... before it turns everything to goo. Like our previous post about the Big Mac getting doused in molten copper, there's something powerful and unyielding in that Big Mac bun.

Check out the eye-opening video.
