One needn't actually DRINK the mercury (or even hold it in one's hand) in
order to demonstrate, or even look at, a mercury delay line. I'm willing to
bet that most of those schools have mercury-switch thermostats everywhere.
Every school I attended did.
Surprisingly, most everything was digital or too simple to contain
mercury at any I went to. Any mercury spill would've been taken seriously. Chemistry
labs still had some
mercury thermometers though, but as expected they were generally avoided. I suppose a
building that was just finished before I went to it isn't a very good
example though...Some of the other buildings were fairly old though. The
expanded and renovated building dating back to the late 1800s was 98%
newer than that, however.
The school even let the kids have x-acto knives and other DANGEROUS TOOLS!
I mean, it was a high school, but I'd still expect someone to go
completely "think of the children!" on everyone. Someone got the
orchestra programme to stop using a church for performances so it's
remarkable we could use such dangerous tools!
Mercury
delay?
That would be cool, but I think schools might have a problem with that these
days. -Dave
