To make a model of a mountain, use a soda bottle or a tall cardboard cylinder as the center of the mountain. Attach cardboard strips from the high point to a wooden or cardboard base. Cover with paper-mache strips and paint.Know More
Cut a 2-foot square base out of heavy-duty cardboard. Alternatively, use a lightweight piece of wood for easier carrying. Paint your base using a solid color.
Find a 2-liter soda bottle, a thick cardboard tube or any other tall and narrow container. Using a heavy-duty glue, attach it to the center of your base. Allow the glue to dry completely.
Cut long cardboard strips about 2 inches wide. Use masking tape or glue to attach them to the top of the bottle. Angle the strips down to the base. For a steep mountain, use a sharp angle. For a bigger mountain, use longer strips and a more shallow angle. Tape or glue the bottom end of each strip to the base.
Mix a paste that is 1 part flour and 1 part water. Stir it well to get rid of any flour lumps.
Coat long strips of newspaper in the paper-mache paste. Lay them horizontally around your mountain frame, making sure to cover every hole. Add extra layers of paper to form cliffs and crags on the mountain surface. Allow the project to dry completely. If the mountain feels flimsy, add a second layer of strips.
Paint the dried surface of the mountain using brown paint. Simulate grass with green paint, or draw on rocks with gray paint. For a wintry look, paint a white snowcap on the top of the mountain.
