The Guillotine

Some cardboard and paper are recycled to make new cardboard, but the primary raw material for cardboard is wood (celulose).
You can make cardboard more durable by adding layers, using thicker cardboard, or applying a protective coating like varnish or sealant.
One can make a robot out of cardboard quite easily with old boxes and a few household items including empty wrapping paper tube, several mini and 1 large empty boxes of cereal, scissors glue and silver paint. First make the body out of the cardboard boxes, the limbs using the wrapping paper tubes and the hands and feet using the cereal boxes. Next paint the whole robot silver and glue the pieces together.
