I also noticed that in the promotional video, the youth who performs the
"volcano" demonstration is not wearing gloves (as he sticks his finger into the
dichromate).

This sounds kind of interesting but I begin to question the validity of the
entire enterprise (especially their stated concern for safety) when I see that
benzene is one of the compounds provided with their kit AND that the MSDS they
offer for benzene not only lacks any mention that it is a known human
carcinogen, but includes the line "Chronic Exposure: No information found." (It
does state "Known Carcinogen" under Section 16: other
information)
It also states in Section 8 that no airborne exposure limits have been
established while burying the OSHA and ACGIH limits in Section 15 Regulatory
information.
I've not checked any of their other MSDS, but benzene is so widely known in this
regard that I have to wonder what these people think they are doing.

Here's something that I think will interest many on the DCHAS-L list... it
addresses chemical safety issues in interesting ways.

This is the chemistry set you always wanted as a kid but either didn't get it or
you got stuck with some cheap plastic wannabe...
