Why do roller coasters (and dips in the road) make my stomach tingle?

Your body’s guts have a lot of give. When you encounter a sudden change in direction and speed, your organs jostle against each other until forces of gravity and momentum reassert themselves and pull everything back into place. Drops on roller coasters (and, to a lesser extent, dips in the road) counteract the forces of gravity and throw your body into a sudden free fall. For an instant, with nothing pushing against it, your stomach rises and you feel that funky sinking feeling that makes roller coasters so much fun and/or terrifying.
