Hiccups happen when
the diaphragm, the muscle that controls our breathing, becomes irritated and
start to spasm and contract uncontrollably. With each contraction, air is pulled
into the lungs very quickly, passes through the voice box, and then the
epiglottis closes behind the rush of air, shaking the vocal chords, causing the
"hic" sound. The irritation can be caused by rapid eating, emotional
stress and even some diseases. The best cure? Breathing into a paper bag. This
calms the diaphragm by increasing the amount of carbon dioxide in your
bloodstream.

to pick up colours.
