When I was TA'ing I started off the term demonstrating the effect of
concentrated sulfuric acid on a paper towel. I think there was much more
engagement with a live demo than with a video.
I noted that spills would be hard to see on the black benchtops and
strongly suggested students wipe them down before placing anything on
them or starting work.
