  If you first feed a bubble then starve it, have proper lighting and
contrasting background, beautiful moving color payyerns appear. The
patterns last about 30 to 60 seconds. To repeat just feed the bubble
film again. If you wet your finger the film can be touched. Moving
pattrensare emitted from your finger tips. Children are completely wowed
from this experience.
  My Rainbow Rivers exhibit is too big for workshops but a smaller
version could be designed for outreach. The images can be captured on
video or with a camera. This could be a great make and Take activity.
   If you are interested I will send you my designs conceptson the
portable version and my drawing on Rainbow Rivers. I also have many
images.
                  There is good science in bubbles.
