Sound You Can See!

You can hear and feel sound waves, but not see them. Right? Well, our new exhibit changes all of that. Sprinkle some sand on the flat surface, press a button, adjust the dials for frequency and amplitude of your choice and "see" the sound waves as the sand is distributed into interesting patterns. 

Thanks to Erik Truedson for developing this exhibit for HSC.
