Kubic Bubble Wands
Grades K - 5. 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. This kit includes a selection of specially made straws and joiners that will allow each shape to be constructed. All materials are reusable.
