ROCK ISLAND — Augustana College's "mad scientist" professors fired up their Tesla coils and plasma globes Friday night to ignite the love of physics, chemistry and biology in the hearts of local Girl Scouts.
About 20 girls between the ages of 10 and 14 donned goggles and lab coats for the Mad Scientist Masquerade at Augustana College's Hanson Hall of Science. The night included demonstrations on the physics behind grain elevator explosions, interactive electrical displays, optical illusions and thought-evoking discussions on the fundamentals of science.
Among the maniacal professors was Pamela Trotter, a biochemistry teacher at Augustana who sported a wild red wig Friday night. As she set up a miniature mock grain elevator with a small candle inside, she explained how the otherwise flammable grains resist the flame -- until they are projected into the air.
Using a long plastic tube, she blew the grains into the air, increasing their surface area and making them vulnerable to the flame. The result was a surprisingly large fireball that rose several feet into the air before dissipating.
"This is the kind of stuff you don't want to do at home," Ms. Trotter said.
One of the girls, Jacee Eddy, of Bettendorf, said she was eager to learn more about science, although it isn't her favorite subject.
"It's actually kinda fun," she said.
Earlene Johnson, the mother of one of the participants, said she thought it was great for her daughter, Shyla, to learn more about science — a subject she enjoys — while also having fun.
"More girls are into science than there used to be," Ms. Johnson said. "They're just as smart as math and science as boys."
Today is Tuesday, Oct. 21, the 294th day of 2014. There are 71 days left in the year.
1864 -- 150 years ago: The weather is discouraging for our great Democratic rally tomorrow, but never mind that. Let our Rock Island people show they can make a big procession themselves, rain or shine. 1889 -- 125 years ago: Apparatus arrived for drilling an artesian well on the premises of George Warner's Atlantic Brewery. 1914 -- 100 years ago: The German army continued its attacks on the allies line near the Belgian coast. 1939 -- 75 years ago: The farm home of Mr. and Mrs. Gus Zachert northwest of Buffalo Prairie, burned to the ground. 1964 -- 50 years ago: WVIK-FM, noncommercial educational radio station at Augustana College, will return to the air tomorrow. The station operates at a power of 10 watts at 90.9 megacycles on the frequency modulation band. The station is operated with a staff of 92 students. 1989 -- 25 years ago: An avenue of lights, 13 Christmas trees strung with more than 44,000 sparkling lights, will expand the Festival of Trees beyond the walls of RiverCenter in downtown Davenport in mid-November.
