  "**From the perpendicular.** Every angle is measured from the line straight through the surface, and the card says so.",
  "**Least time.** The bent path is the quickest one for light; THE LEAST ACTION CARD shows the same idea for motion.",
  "**Turned back whole.** Past the critical angle no light gets out; the card says so instead of printing an angle.",
  "**Colours differ.** Water's index changes with colour, which spreads a rainbow; the card uses five measured values.",
  "**Both bows.** The second rainbow sits near 51° with its colours reversed; the dark band between them is real.",
  "**Named or numbered.** Materials by name or by index; an index under 1 is refused."
