My Chem prof used to toss back shots of liquid nitrogen.  He'd pour a shot,
toss it back, gargle with it and this enormous plume of nitrogen fog about a
meter and a half high would just fountain out of his mouth.  The /hard/ part
is not letting any hit your teeth, because the effects of LN2 on enamel are
catastrophic.
