A practical way to visually "prove" geometry problems and demonstrate light refraction. Build cubes, octahedrons, tetrahedrons, and prisms- then dip them in soap-glycerin to produce fascinating shapes with the smallest possible surface areas. Instruction booklet explains formation of surfaces by each of the frames and examines properties of soap films. The secondary kit includes red, blue, green and gray tubes to make a cube, a octahedron, a tetrahedron, and a prism, as well as 2 perplex plates and 6 suction cups. This learning kit is perfect for classroom use or at home learning, recommended for grades 7 and up or ages 12 and up.
