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,

 

  1. 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.
  2. I shared this information with a colleague who said he does the demo without this precaution and everything is always fine.
  3. Being cautious, I rely on videos to show rather than demonstration.

 

Best regards,

 

Ruth Ann

EXTERNAL 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, 

Thanks,
