Why are there only 5 perfect 3D shapes? Their secret is the basis of nearly all natural and human-built structures. Build all five of Plato?s solids in relation to their duals:
• Tetrahedron (4-faces)
• Cube (6-faces)
• Octahedron (8-faces)
• Icosahedron (20-faces)
• Dodecahedron (12-faces) is the shape reserved for the cosmos!
• Great for beginners
• Includes detailed instructions
