Whats the difference between a smoke machine and a fog machine?
The terms ‘smoke machine’ and ‘fog machine’ both refer to the same type of unit. ‘Fog machine’ is the term used more in the United States, and ‘smoke machine’ is the term mainly used in the United Kingdom and Europe. Technically, the correct terminology is ‘fog machine’, as the dictionary definition of fog is ‘liquid particles suspended in the air’ (smoke/fog machines always vapourise liquid), whereas smoke is ‘solid particles suspended in the air’. The effect generated appears to be that of smoke. Tradition along with product descriptions over the decades has created this moniker foible.
