The 'Es Liegt was in Der Luft' copper clock is the design work of Patrick Palcic and is intended to tell time in an unorthodox: by emitting different scents. The 'Es Liegt was in Der Luft' clock, which translates to "There Is Something in the Air," works by having different scents emit through the various holes that are strategically placed around the clock face on the hours.
Each hour emits a different scent from the 'Es Liegt was in Der Luft' copper clock with the various fragrances pertaining to a feeling and essence. This means that the morning hours will be refreshing and light, while the ones in the later hours of the day will be more relaxation and erotic in smell.
