Caption

Cheeseburger in hydrochloric acid. Timelapse footage of a demonstration being carried out to show a cheeseburger being dissolved in a beaker of concentrated hydrochloric acid (HCl). The acid breaks down the bonds in the food molecules, which include proteins, carbohydrates and fat. The acid used here has a concentration of 12M (molar) compared to the 0.7M of stomach acid. In the stomach, the acid also activates food-digesting enzymes. The middle section of this clip has been speeded up. In real time, this process took 22 minutes.
