Chemistry Majors Blow Things Up for WesFest

The annual WesFest chemistry demonstrations show, (Barely) Controlled Substances, was held on Apr 12 for a large and appreciative crowd of visitors and Chemistry Department hangers-on. The demonstrations included the classics gun cotton and thermite, as well as exploding hydrogen/oxygen bubbles, elephant toothpaste, a chemical oscillator, and others. The Chemical Demos Student Forum (Shelly Duong and Victoria Yu as student leaders plus David Cabanero, Leticia Costa, Jessica Garcia, Allie Goss, Sojeong Park, and Kate Sundberg) treated the survivors to liquid nitrogen ice cream afterwards. Pictures and a link to a video (compiled by Shelly Duong and Chloe Qiu) are below.

Kate Sundberg ignites an inordinate amount of gun cotton, which is always a crowd pleaser.

Leticia Costa demonstrates the catalyzed decomposition of hydrogen peroxide to give “toothpaste”.
