Materials

  • A string attached to two small spools.

Preparation


Presentation

  1. The directress, unseen, places one spool in each hand and closes his fists so that the spools cannot be seen.
  2. The string passes between the fingers of each hand.
  3. Placing the fists together, the children are invited to watch.
  4. The directress unrolls the spools as the hands are separated.
  5. This is a line, this is a line... As the line grows, the directress changes its position continuously - horizontal, vertical, oblique - still identifying it only as a line.
  6. Finally, with the string taut, this is a straight line; and with it drooping, this is a curved line.
  7. "A line" cannot exist by itself; it must be straight or curved or a combination of both.
  8. Any line that I make will have one of these qualities.
  9. The concept of a line goes infinitely in both directions.
