I first saw this a couple of weeks ago. Inspiring doesn't somehow cover the ingenuity and desire behind this venture.
Reminds me of the time we once made a drum kit from some five gallon paint tins, some draughting plastic a few sticks and some (strong) string when I was on board ship. Full drum kits were not readily available onboard medium sized naval ships at the time!!
Just goes to show that where there is a will there is a way!
Good luck to the children, teachers and instrument makers this Christmas and good fortune for the coming New Year.
