Aerosol: a pressurized substance, released as a fine spray, by means of a propellant. 

Aerosol contains small particles, liquid, or solid.  These tiny particles are suspended in a gas. 

The word may also mean the container itself. 

Aerosol, first used in 1919, comes from Greek ἀήρ (air), and Latin solvere (to loosen). 

Worst aerosol idea ever…
