Cut a hole in the lid of a plastic container. Make four holes for the strings. Cut a notch into the side of the container, where you will slide in the wooden slat.
Spray paint the container and the wooden slat. Let dry.
Use paper tape to make frets on the wooden slat and then glue tuning pegs, made of lolly sticks and beads, to the top of the slat.
Slide the wooden slat through the notch on the container. Push it all the way in and then glue it in place.
Attach beads to the holes in the lid; use a piece of string and attach one bead to the inside of the lid and one to the outside. Stretch a rubber band around the knobs.
Bring out your inner rock star with a home-made banjo! Find a plastic box with a lid. Cut holes in the plastic box: one for sound, and for the strings and a wooden slat, the neck of the banjo. Spray paint the box and wooden slat any colours you like. Attach big beads to the small holes in the lid. Use sturdy string and attach one bead to the inside of the lid and one to the outside. These will make stable knobs around which to stretch the rubber band. Add lolly sticks, paper tape and beads to the neck of the banjo. Use a hot glue gun to attach the different components.
