Prisms are a classic science teaching tool because of their excellent refractive properties. Equilateral prisms are the best for creating beautiful spectra. Right-angle prisms can demonstrate total internal reflection, neatly turn light beams 90 degrees (use two to build a periscope) or split a single laser beam into two!
