I saw this last week and posted in the comments sections concerning how
ill-advised and unsafe this was. I couldn1t tell from the video if all if
the students even had closed-toed shoes. This does remind me of the CSB1s
discussion of chemical demonstrations earlier in the academic year. I1m
not saying that there necessarily should be 3demo police2, but some kind
of hazard analysis should be required before putting students (or anyone)
in harm1s way in this manner, in my opinion.
