Ever had a music project at school or just wanted to fool around with tuning and playing a guitar but guitars are just too expensive well I have the perfect solution for you this is a fully tune ready one string guitar it's even good for the environment.
The materials for this project are a soda bottle thethe bigger the better
A string big enough to wrap the bottle twice from cap to bottom
A knife or scissors ( I like the scissors )
Tape optional not needed but helpful
One electric drill
