Today I learned one can build a violin with nails instead of strings. The idea is as simple as genius. You take a block of wood, your violin bow, a few nails and a hammer. You take the nails and depending on how deep you drive it in, it’ll make a different sound, when you bow it. If you take a bunch of nails and a lot of time, you can make a well sounding violin which is fully playable.

I came across that, after watching a video about PVC pipe instruments by the same artist. Always amazing what people do around the world. It’s simple and it seems to be fun to play and the materials are cheep, maybe you try it build a simple version with kids some day.
