Liquid Nitrogen

After rafting, we went back to mom and dad's for a barbeque. Their friend Greg was there with his wife. He is a Physics professor at MSU. He brought a tank of liquid nitrogen with him!

He also had some homemade ice cream mix in a 5 gallon bucket. He had Charlie slowly pour liquid nitrogen into the bucket while he stirred it.


After only about 10 or 15 minutes (instead of the usual hour to hour and a half) we had homemade ice cream. It was delicious too.



Afterward, Greg had a bunch of liquid nitrogen left over. He certainly couldn't let it go to waste, so he amazed us with some experiments. It was a good way to finally end the day.
