Design Challenge: Make Your Own Instrument (video)

Video description:

"How do you make an instrument from scratch?
Today we’ll be playing with a song you already love. What's a tune you played over and over as a teenager? Do a Google search for the track online. Choose particular sound in the song--we’re going to make an instrument for it.

Instrument must reflect a unique sound from a song of your youth.
It must play more than 3 notes.

Take a video of you playing the instrument that lasts more than 30 seconds."
