Making your own Tonoscope: Visualising Vibrations at Home 

Follow this link to our video on an experiment you can do with instant coffee: • Another Cup of Coffee:...
Surfaces vibrate in different ways, depending on the frequency/frequencies they are shaken at. Ernst Chladni was a German physicist to first demonstrate this, by running a bow along a thin plate with flour on it, that made unique patterns when vibrating at different frequencies.
Learn how to make your own Tonoscope, to visualise vibrations, and send us photos and videos of yours in action!
