It is more likely to occur in persons who regularly have raised pressure in the mouth, for example wind instrument players, [6] and balloon [1] and glass-blowers.

The Valsalva maneuver is performed by a forceful attempt of exhalation against a closed airway, usually done by closing one's mouth and pinching one's nose shut while expelling air, as if blowing up a balloon.
The balloon trick To do this, blow up balloons in warm air, then expose them to cold air and they will deflate. Eventually they will reinflate when you return them to warm air.
If these small airways and alveoli are allowed to collapse, significant pressures are required to re-expand them. This can be explained using the Young–Laplace equation (which also explains why the hardest part of blowing up a balloon is the first breath). Entire regions of the lung that would otherwise be collapsed are forced and held open.
Fire breathing is the act of making a plume or stream of fire by creating a precise mist of fuel from the mouth over an open flame. Regardless of the precautions taken, it is always a dangerous activity, but the proper technique and the correct fuel reduces the risk of injury or death.

Thus, a "260" is 2×60 inches and a "160" is 1×60 inches when fully blown up.
