Subject: Ruben's tube and propane

Post:

One of our faculty wants to use my Ruben's tube as part of a road show
to a high school. The school does not have a natural gas source for
him so he wants to rent a propane tank to fuel the tube. I am
concerned about: how well this will work, as I seem to remember that
propane requires different sized orifices for flame jets than natural
gas, safety (a tank of gas under pressure near an open flame in front
of a large audience) and finally, in our lecture hall use, I find I
have to turn off our air handlers to reduce air currents in the room
so the flames are stable.

So I was wondering if any of you had experience using the Ruben's tube
on the road in such circumstances and had any advice for me to pass
along.
