    The same way you feel cold when you get out of the shower wet.
    Liquid needs energy(heat) to change to a gas(evaporate).
    The duster absorbs a lot of heat so it feels much colder.

    I think a lot of it has to do with the duster going from very high pressure to low pressure very quickly.
