The Post-Tribune reported that Fermilab’s “Mr. Freeze” gave a cryogenics demonstration to a group of home-schooled students at the South Lake Church of the Nazarene in Crown Point IN.
Jerry Zimmerman (Mr. Freeze) is an engineer at Fermilab and has given these demonstrations all around the Chicagoland area for the past 13 years. In November of 2008, he presented his cryogenics show at the “We Build Cool Stuff” open house at Meyer Tool, an event co-sponsored by the Cryogenic Society of America as part of the year-long Science Chicago celebration.
As part of the show, Zimmerman made bags, balls, and bottles explode after filling them with liquid nitrogen. He also froze flowers and bananas, surprising the crowd of students. But the biggest crowd-pleaser was the liquid-nitrogen-dipped marshmallows handed out at the end of the demonstration.
“Fermi does these shows because science education is very important in letting the public know why we need scientific investigations,” Zimmerman said. “I feel there is a real lack of science education in the classroom, and without good science education in our schools, America is going to fall behind.”
