This week, one of the projects was to have someone teach you something. Grandson, Nathan, had been to a Science Fair, and had been wanting to make a volcano that would erupt. So we constructed a volcano out of clay, with him giving the directions. He decorated it with leftover scale model materials from our golf course and subdivision model making days. He wanted to have vehicles in the way of the lava flow, so while he worked on the vehicles, I placed the dinosaurs on the grass and snapped a picture. Then it became his project - soda and vinegar with some red food coloring made a pretty spectacular eruption and wiped out the railroad and grass! I have a video of the eruption, but can't get it to load...maybe later.
