- A string attached to two small spools.
Preparation
Presentation
- The directress, unseen, places one spool in each hand and closes his fists so that the spools cannot be seen.
- The string passes between the fingers of each hand.
- Placing the fists together, the children are invited to watch.
- The directress unrolls the spools as the hands are separated.
- 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.
- Finally, with the string taut, this is a straight line; and with it drooping, this is a curved line.
- "A line" cannot exist by itself; it must be straight or curved or a combination of both.
- Any line that I make will have one of these qualities.
- The concept of a line goes infinitely in both directions.
