I had a spare hour during my lunch break so whipped up a quick Golden syrup can 2 stringed ukulele thing? I used a handle from a walking stick, a golden syrup can, 2 picture frame hooks to anchor the strings from a badminton racket.
The quality is rubbish, and the audio goes a bit weird towards the end for some reason, but you get the idea! Next one I shall have to try on a different camera.
