Trevor is really into "science" these days. Here he shows off a project he took from his kids science project book. He did it all by himself with no input or assistance from us. Read the directions very carefully and did each step. As for what it is, I am not sure. Basically he used his play doh to attach a funnel to a pop bottle. His next project.......a worm farm....stay tuned to see if we actually make one.
