German designer Markus Kison invented a device that lets people experience the atmosphere of WW 2 nowadays.

Set up in the German city of Dresden, Markus Kison’s so-called time machine takes people back to the 13th of February  1945 when bombs were dropping all over the city and the whole country was in chaos. But the most remarkable thing about Kison’s invention is the way it operates. It’s not just some ordinary siren that emits sounds of bombing, it operates in complete silence. People just have to put their elbows on the iron fence on witch the device is installed and cover their ears with their palms. The sound is transmitted through vibrations that make their way through the bones until they reach the ears.

Fascinating invention by Markus Kison!
