If you are doing a power box, like what was attached to the E-WEB in the movie, you could easily set up the fog machine, an RV battery and power iinverter to do all that. It could all be safely concealed within the power box of the E-WEB setup. Of course that could get spendy as power invertors are what $70? and the RV battery can be just as much?
If there is access to an electrical outlet, you could still do the fog machine hidden in the power box. Since there was a big tube connecting from the box to the E-WEB, that would be a great conduit to transfer the smoke from the hidden fog machine in the box to the E-WEB blaster, itself.
Know what I mean?
