Did you know that the diaphragm is the one usually behind hiccups? The diaphragm is a muscle located below the lungs. It contracts when you breathe in and relaxes when you breathe out. But sometimes it can get irritated like when you eat too fast. It causes the muscle to contract in a jerky way and the air rushing in becomes blocked by the closing of the epiglottis (located by the vocal cords). So you end up making a hic sound. :P
