These are some homemade stringed instruments. There was a woman there trying out the one on the far left. It sounded pretty good. While she was playing it, the instructor for the class said, "I see we have a cello player here." The middle one is suppose to be an erhu made from a broomhandle and a Peet's Coffee tea tin. The bow should be in the middle of the two strings but it's not. It still sounded ok though. You can see from the pegs that the one on the right is an 9 stringed instrument. The strings curved around that wood dowel sticking out of the bottom on the coffee can. The neck was made from a branch of a tree.
