Holy cow, I wrote a book!
Professor Hubert Alyea would be 110 years old today, if he
were still among us.
passed away in 1996 at the ripe age of 93.)
LIFE magazine called him
the science teacher you wish you had
for his engaging (and often explosive) chemistry demonstrations.
He was called an
"international grand master of lecture demonstrations"
noted chemist and
on chemical demonstrations.
I had the immense good fortune to attend one of his lectures.
As he prepared his equipment,
he casually popped a piece of dry ice in his mouth.
(DO NOT TRY THIS AT HOME.)
You can see a demonstration at the start of this video:
"Professor Alyea, how can you handle dry ice like that?"
He spit out the dry ice and replied,
"Oh, I'm not handling it. I'm putting it in my mouth."
Here is a VHS recording of his lecture
Lucky Accidents, Great Discoveries and the Prepared Mind.
The lecture concludes at 25:15 with a series of reactions,
culminating in his signature demonstration.
The colors don't show up well in the video, so you'll have
to trust that they are what he says they are.
