<p class="MsoNormal"><span style="font-size:11.0pt">For the budget- and access-impaired on the list (we can’t easily get dry ice or liquid nitrogen, even if we wanted to), we’ve had some success making low-lying fog by pushing regular glycol fog through a heat
exchanger (i.e. dryer duct coiled in a cooler full of regular water ice) with an inline fan. Not as good as machines made for the purpose, but pretty cool.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">If your fog machine regularly trips your alarm system, I’d approach it as two problems – first, creating the low-lying fog to suit the show and second, finding a solution for the alarm trips – disable and
fire watch, change the detector type, etc. – so that you’re not relying on atmospheric conditions to avoid stopping your performances. Helps to have a cooperative and supportive AHJ and Facilities team, which we’ve been fortunate to have.<o:p></o:p></span></p>
