I was shopping at a grocery. A bunch of avocados caught my eye. For months I had been tinkering of a perfect form and the mechanism for the musical instrument to help our ASD students destress. And there it was, sitting right in front of me! Instantly I knew the avocado would be a perfect shape for handling, its anatomy (with the seed removed) would give me the collapsible air chamber for housing the beads, and its flesh would be good for squeezing. And so the Avocado was born! A shaker like this could help our ASD students. It you squeeze it too hard, the air chamber will collapse and shaking it won’t make a sound. It’s almost as if the shaker is telling you, “Relax, if you want to be heard!”
