What I like about this project is the aesthetic effect you get from the bright candy displayed in the glass jar. Everyone, especially kids love it. Alterations that I would make would be to use a larger glass jar. Also if you look at the bit of wood that you push or pull to get the candy. I would put a dowel through that. The dowel would stick out at the top and bottom. It would act as a handle to make using the dispenser easier. The key part of the build is that round piece of wood he uses to funnel the candy into the hole. If you don’t have that not all of the candy would come out of the jar.
