Our main goal for one day was to build a tetra box lamp out of juice cartons. It did not turn out so well. We ran out of time to build the whole thing out of juice boxes so we ended up making most of it out of cardboard then cut triangles into it. But we still managed to make the bottom out of juice boxes. About 2 hours of our time went to cutting the juice boxes and cleaning them. I think we should have cut the juice boxes in half before One Day so we had more time. It also took us a while to make the strips and to hot glue them together. David and I both got burned with hot glue a couple of times during the process of hot-glue the pieces together. When we had about 1 hour left, we had to quickly cut the cardboard into shape then carve the triangles into the cardboard. We Hot-Glued in the lamp on the top with the batteries so it would light up. We also hot-glued a piece of string to the top so that we could hang it from a hook.
