[DCHAS-L] Chemistry Demonstrations
Craig, Like the song says: Thanks for the memories. But it also opened a lot of old wounds for a woman who was in chemistry at this time. However, I'm going to use two short snippets from the video for my class which illustrate the pentagram diagram of deflaggration with confinement v. the quadrangle of deflaggration without confinement using flour and a candle. And since the first deflagration explosion in recorded history was from flour in a bakery in Italy in 1785, it's appropriate.

All,
There have been great discussions on this list-serve about chemical demonstrations. So here is a video that harks back to a bygone era.
This video could be used in a safety class asking students to identify all the things done wrong by modern safety standards. Dozens!
The sexism is also stunning as this was from 1955 and Princeton University did not admit female students until 1969.
