This cheeseburger vs. acid experiment by YouTube channel Periodic Videos is a classic, from way back in 2010. But it’s still one of our favourite YouTube experiments of all time, and we thought it was definitely worth bringing it out of the archives for any of you who may have missed the truly revolting results.
The set-up itself is pretty simple – take one McDonald’s cheeseburger and stick it in hydrochloric acid in the lab for three and a half hours to see what happens.
Why hydrochloric acid? Because it’s one of the main ingredients in our stomach acid, which kick-starts the digestive process and helps us break food down into useable components that give us energy and nutrients.
Or, at least, that’s what happens in theory. In reality, what it does to the cheeseburger is a little less stomach-friendly, as you can see in the footage above.
