Test:
Once an Allomancer has Snapped, they will feel a reserve of power in their stomach when they have ingested a metal they can burn. The metals are usually ingested by drinking specifically prepared metal vials, which contain metal flakes in an alcohol solution. It is completely instinctual for an Allomancer to activate and burn their metal and gain its ability; it does not require training to do it (however, there is much training in using their metals properly). It is so instinctual that in some circumstances, an Allomancer can even burn metals while unconscious. An Allomancer can also burn their metals at an accelerated rate, which is called "flaring" metals. Flaring grants more power, but the reserve of metals depletes much faster, too.
