Helium E Tank
E Helium Tank. 90 cf tank fills approximately 160 12″ balloons.
Chauvet Hurricane 1800 Flex Fog Machine. Includes wired remote with automatic and manual functions. 25,000cfm output. The full 5 liter tank of fog fluid will last for 40 minutes of continuous use. Since you would never use this machine continuously, but rather on the timer delay, the fluid will last exponentially longer. Example, If you programed the timer to do a 5 second burst of fog, in every 30 second duration, the fluid on a full tank would last approximately 6hrs. May be sensitive to some smoke detectors that measure particle air density.

M helium tank. 37 cf tank fills approximately 60-12″ balloons.
