"a thermobaric bomb can create overpressures equal to an atomic bomb"
a dispenser that holds a substance under pressure and that can release it as a fine spray (usually by means of a propellant gas)
An early design for an aerosol can: a refillable hand-sized steel can charged with a pressurized liquefied gas and a product to be expelled as a mist or a foam.
