Quoted from pinballrockstar:
This is the rc smoke machine for the ufo , we will be the first ones with a smoking ufo for dramatic effect.
Leds will illuminate the smoke under the ufo and after the mode,a cabinet fan will suck the smoke from the playfield real quick through the back and out the machine.
