How to Make a Cardboard and Sand Pyramid

Create a sand pyramid for your school project.

Take a cue from the ancient Egyptians when you make a cardboard and sand pyramid and build a model of the Great Pyramid of Giza. While you can’t replicate the massive size for a school project, you can build a pyramid with four sides and a base on a sandy plateau for it to reside. You can find all the materials you’ll need at the local art supply store and home improvement center to create your project.

Place a piece of cardboard on a flat surface. You can find single pieces of cardboard at home improvement stores or you can cut up a large cardboard box.

Squeeze lines of white glue all over the cardboard. Spread out the glue in a thin layer with the paint scraper. Pour sand over the glue. This will form the base of the pyramid. Let this base dry overnight.

Draw a 12-inch square in the middle of the other piece of cardboard, using a ruler to make even lines.

Measure two lines of a 12-inch equilateral pyramid above the square, using the top line of the square as the bottom line of the triangle. Repeat this step to make three more triangles on all sides of the square.

Cut out the entire shape with the craft knife. The shape resembles a star, at this point.

Fold up each triangle side, one at a time to form a pyramid. Tape the sides together with the masking tape.

Glue the bottom of the pyramid to the sandy base. Press the cardboard down gently to secure it to the base.

Apply rows of glue one side of the pyramid. Use the paint scraper to spread the glue into a thin layer.

Sprinkle sand all over the glue, covering the glue completely.

Repeat steps eight and nine for the other three sides of the pyramid.

  • Use strong, corrugated cardboard to support the weight of the sand.
