Before any experiment we choose our instruments with great care but then we randomly use them. For this reason, we never know what the experiment has in store for us and there are always surprising and interesting revelations. This time, as we were playing along, we noticed how unpleasant the sound of things hitting glass surface are so we agreed on avoiding that material in the future. On the other hand, among the pleasant noises there were some outstanding ones. Who knew that rubbing soup pearls would be so satisfying or crushing rice would bring back memories of long walks on Croatian gravel beaches?
