In the Workshop with Grandpa

Daniel had a project at school.  He was to come up with an invention to help him with a problem he was having and then build the invention.  Daniel has these sneakers with ridges on the soles; he decided to invent a shoe cleaner that would take the dirt out of the ridges.  He came up with the design, we went to HomeDepot and bought all the parts, and then he and Howard put it together in Howard's workshop.  It was fun for everyone.   And, his teacher and class loved it!
