How instructive is a video of some guy who says nothing more than "Don't
do it" without anything to back up his words other than some videos of PVC
bursting after being subjected to...oh, wait...we have absolutely no idea
what it was subjected to. Bad example.

No, not at all but you're welcome to experiment with your life.

Here you go...

How about I post this video with the warning "Never, ever, ever fill
your tires at a gas station!". I'll make sure I label it as "instructive".

I'm pretty sure that you, being the intelligent gent that you are, would
be one of the first to point out that we know very little about the root
cause of that explosion. Our *experience* tells us that the situation is
out of the ordinary, therefore we wouldn't consider the video to be
"instructive" as it relates to the "Never, ever, ever" warning given.

Regarding the PVC video linked to above, we don't know if they tested that
PVC with 60 PSI or 600 PSI. To be considered "instructive" (and that *word*
is the only thing that I'm talking about) the video needs to tell us
something about the test conditions.

To be clear, I am *not* recommending or even suggesting that PVC be used
for air under any conditions. My only point is whether or not those videos
can be considered "instructive" in the context used.
