On the fume hood, I assume the color-coded taps for yellow & blue are gas & water, respectively. What are the other 2?

@bluecollarcanuck the other two are vacuum and steam

You, sir, have an awesome shirt.

@ihoppy You can also get the reuseable blue gel packs found in physiotherapists' offices.

Would have been nice to actually see the thermometer. You say in the vid, "you can see" but I can't. Maybe have the cam zoom in on what is happening. All I see is a guy in a nice shirt.

@ihoppy you can get them from various places a quick search found campmor sells similar ones

It says to boil them but in the past we have had issues with the outer pack melting a bit so we simply use warm (~80 C) water
