Build A 3D Rainbow

Materials Needed:
Play dough/clay (white or black)
Pipe cleaners (red, orange, yellow, green, blue, and purple)

What to Do:
Starting with orange; cut 1 inch off the end of the pipe cleaner.
Next cut 2 inches off the end of the yellow.
Continue in this manner (following ROYGBP), cutting an additional inch off for each descending color.  If done properly, purple will be 5 inches shorter than red when finished.
Invite the children to use two balls of clay spaced about four inches apart.
Provide cut pipe cleaners and encourage children to create a rainbow by sticking the ends of the pipe cleaners into the two balls of clay.

*We eliminated the indigo and violet in the ROY G BIV and chose to use purple in place of them.
