Design your bridge on paper or a computer program, then use skewers and glue or string to construct the parts of the bridge and assemble them. Decide on what type of bridge you want to build. Follow a common bridge design style, like a beam or truss design—or come up with your own.
Model bridge building is a popular pastime, where hobbyists create bridge models from various materials like spaghettis, toothpicks, cardboard, skewers, balsa wood, etc. Miniature bridge making is also often used in education in areas like physics and engineering.
