The theremin was invented 100 years ago, but musicians and performers still struggle to wield the magnificent instrument, that seems like something from the future. In this performance, the amazing artist and composer Dorit Chrystler will demonstrate the power of the instrument and let us all experience the power of music and understand the advancement of science that allows the creation of the theremin.

Join us in the afternoon in the Science Pavilion in the Beer Bongs and Bosons lounge where the first round is on us. We’ll be asking you questions like ‘why is the foam on a brown ale white?’ ‘why is a Gin&Tonic luminescent under UV light?’. Right or wrong answer, we’ll tell you stories and reveal the magic of alcohol.

We all need electricity in our daily life, but where should it come from. One place we can harvest energy is the power of the suns electromagnetic rays, and it is something we harvest on large scales. This is your change to try to build your own charger driven by solar power. How difficult can it be....
