What Is the Science Behind Hiccups?

Hiccups happen when your diaphragm suddenly contracts, which makes you inhale quickly, and then your vocal cords close, making that hic! sound. It's like a little surprise party in your chest! Sometimes hiccups start because you ate too fast or drank something cold. They might stop on their own after a while, but if they keep going, it can be annoying!
