I let down my tough guy vice principal persona at work for a few minutes this morning to have a little fun with helium. Students at my school took the science portion of the California standards test today. As a fun way to pump them up, me and one of our science teachers finished making the morning announcements by introducing what portion of the test they would be taking after taking a deep breathe of helium (me) and sulfur hexa flouride (Chris Fuge). The Sulfer has the opposite effect as the helium as you will see. I asked students later on what they thought and they said they had a tough time understanding me because of the high voice (This is where my brother Matt chimes in and says something like, "sounds normal to me"). The video is poor quality, but you can get the idea.
To use the helium well, you have to take a deep breathe, expel all your air, breathe the helium deeply and hold it. I started this process a little early as my principal was not quite ready to hand over the mic and ended up holding the helium a little early and way too long. As a result, my lungs started to hurt and I started to feel a little lightheaded, I can't remember the last time I sucked in helium. Oh well, It was fun while it lasted now back to being the tough guy.
