That is the most peculiar thing I've heard in a LONG while. Any chance of getting a copy of that video? Monona

Hi, Melinda,
- In teaching the Physics of Music, I used a text with accompanying videos by an instructor from the Univ. of Maryland. This was some years back! In a video he inhales SF6 and then explains
the need to hang upside down from a table to let the heavy gas get out of his lungs.
- I shared this information with a colleague who said he does the demo without this precaution and everything is always fine.
- Being cautious, I rely on videos to show rather than demonstration.
Best regards,
Ruth Ann

Exercise Caution
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,
