What Causes the ‘Burning Feelings’ of a Pepper?

Peppers feel like fire because they have a special chemical called capsaicin. When you eat a pepper, the capsaicin grabs onto your tongue and sends a message to your brain that says, 'It’s hot!' This makes your mouth feel like it’s on fire, even though nothing is actually burning. It's kind of like getting tickled by invisible fingers, you can’t see them, but you feel the fun (or in this case, the heat).
