(Note by Mom: The Utah Museum of Natural History at the U of U is free on the first Monday of every month, which is a great deal in any one's book! They also have a Phun with Physics program on the first Monday that is highly entertaining and educational. We definitely recommend it!)
For Family Home Evening we went to the Museum of Natural History. They did a show downstairs where they put a ball in liquid nitrogen. They then did a bouncing contest and we all went outside to the front steps of the museum. They thew the balls up in the air and when the ball that was soaking in the liquid nitrogen hit the ground it shattered and broke into different pieces. I thought the show was cool!
