Festival of Molecules

Amid glorious summer weather, the Festival of Molecules was held in the University of Basel’s Kollegienhaus at the end of August. According to a press release from the University of Basel, over the two days of the festival around 80 school classes and more than 4,000 visitors attended this interactive exhibition on the fascinating world of chemistry. The SNI was represented, along with the Department of Physics, by a stand focusing on the topic of color. Children, young people and adults had the chance to split white light into the colors of the spectrum using a spectrometer they had built themselves, and then to produce white light again from the three primary colors – green, red and blue – using a gyroscope. Also very popular were the laser chess and polarizing films. By sticking pieces of tape all over these films at random, you can generate some quite amazing color effects.
