Expandable Gurio

by corben33

Guiro - a musical instrument with a serrated surface that gives a rasping sound when scraped with a stick, originally made from an elongated gourd and used in Latin American music.

They decided to not try and design something that just made noise, but something that could be utilized in an educational setting as well. So they went and spoke with the music teacher and they came up with the idea of a Guiro. I then instructed my students to research what a Guiro was, and where it originated from. After doing their research, my students then began sketching out their ideas which led to the idea of making this instrument expandable. Students wanted the people who made this to be able to add two or more Guiros if wanted. Overall, I am very impressed with what my students and I were able to come up with.
