Stomach acid is one of the most acidic substances in the world, having a pH of just 1. It's so acidic that it can dissolve many metals. However, the enzymes in your stomach are incapable of digesting plastic, so if you swallow some plastic, it's coming out exactly the same on the other side.

Equilibrioception is our sense of balance. Thermoception is our sense of determining what the temperature is outside. Nociception is our ability to feel pain.
