Does anyone have experience with these? This won't make it into my haunt this year but Id like to get some info if anyone has it.

The video shows a commercial jet but i found these photos which looks like someone might have pieced one together with just a large solenoid (like you would find on a typical ankle blaster). Not sure if you would want to make them your self since your dealing with high pressure but if you were using a standard high pressure tank regulator I'm sure you could get it down to a safe working pressure for the solenoid.

Also trying to find out how long a 125 cu ft tank or 250 cu ft tank would last?

any info would be helpful
