Peru, Nebraska – Chemistry faculty and students from Peru State College put on their annual Mole Day magic show on October 29.

Mole Day is an unofficial holiday celebrated among chemistry enthusiasts on October 23, between 6:02 am and 6:02 pm. The day commemorates Avogadro’s Number (6.02 x 1023), a basic measuring unit in chemistry. The event was postponed to October 29 to better fit visitor schedules.

The flame has erupted into a mushroom cloud. The student holding a double-handful of fire looks nonplussed. It is impressive.

After a meet and greet in the conference room, students and teachers conducted several chemistry demonstrations that double as magic tricks. This included turning a normal fire green and using a trash can to blast plastic cups off of audience member’s heads.

Dr. Nathan Netzer, assistant professor of chemistry, remarked on the crowd, saying, “Mole Day had a large student turnout. I enjoy seeing the reactions of the students to our chemistry presentation.”

Dr. Dennis Welsh, professor of chemistry, said “Mole Day is the unofficial national holiday to celebrate chemistry. Peru State has been celebrating Mole Day for more than 15 years.”

“We average around 80 students, faculty, and staff attending our demonstration. I personally love Mole Day because it lets our community make the connection between the knowledge and fun of the STEM fields.”

Attendants of the school’s magic show also munched on different mole themed foods throughout the performance, such as molasses cookies, caramel corn, guacamole, and Avogadro’s dip & chips.
