Our experiment didn't work... We were thinking why... sound is caused by a vibration and we should "see" sound waves... students gave their hypotesis why the small balls didn't dance this time... as in Romanian video... perhaps not enough balls, pehaps the tone or frequency of the sound was not good, perhaps it was too low...
