Description
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 kit contains components to construct 2 each of the following four shapes: Tetrahedron, cube, octahedron, triangle. ( EDU886 )
