Any thrill-seeker who has visited an amusement park would be able to describe (probably in detail) the adrenaline that comes from being on a roller coaster. The high speeds, the wind, and the inescapable feeling of being flipped upside down in a loop–all of this adds to the thrill! But if you've ever taken a closer look, you'll notice something rather interesting: those loops aren’t perfectly round. In fact, they're not circular at all.

This design choice isn’t just about aesthetics—it's a clever combination of physics and engineering that ensures the ride is as safe as it is exhilarating. So, what’s the science behind these non-circular loops? Click through this gallery to find out.
