Melinda,
Is this the inhalation of SF6 and helium gases then speaking? Maybe you should have mentioned that in your post. It seemed like a YouTube idea to me. (Tony liked some of those as an undergraduate.)
Cost is a big issue. Source cost and disposal cost. A lecture bottle might be in the hundreds, but the disposal of the bottle is in the thousands. And, is there a safe lecture bottle regulator? A cylinder from Roberts (and a regulator
if it doesn’t take the N,He,Ar regulator would last forever so you would be paying cylinder rental every year.

Hello, everyone,
I have been tasked with investigating procedures for use of SF6 for lecture demonstrations. So I wanted to check in with you all to find out if you have any experience with supplying or supporting this demo and if so what tips, pointers,
precautions, and/or prohibitions you might be willing to pass on.
Any help or info much appreciated,
