Ancient way to visualize the effects of vibrations on mechanical surfaces. Chladni patterns were discovered by Ernst Chladni

Material required: speaker, Metal/ plastic plate, sand etc.

Description: Place the Metal/ plastic plate on the speaker. Balance the plate and Sprinkle some of the " sand" on the surface of plate. Turn the speaker on and adjust the frequency until a standing beautiful wave pattern can be seen on the surface of the plate. The sand will gather into the null areas of the plate. 



One can also create such patterns with the help of guitar, violin, and vibratos with electronic signal generator.
