Title: Interesting video of sand patterns generated by specific tones Post by: M Benesi on July 26, 2013, 10:25:57 PM I'm wondering if the patterns generated are related to weight/density/volume/shape of the sand grains used?

It's just a question of resonance. Standing waves will form at the right frequency and the sand will migrate to the nodes of the standing wave |
