What does it feel like to get sprayed by a fire extinguisher?

@Senegoid

It contains compressed CO2, which expands massively as it is discharged. Expanding gasses get very cold, and this will get cold enough to cause frostbite. (Here’s an experiment you can do at home: Open your mouth wide and blow gently into the palm of your hand. Note that it feels warm. Now purse your lips and blow gently into the palm of your hand. Note that it feels cool.)

Suffice it to say no one believes you can pressurize air significantly by puckering your lips.
