Description

Amaze your students with a colorful, fun experiment.
Materials and chemicals are provided to make
cyanotyped material on cloth or paper. The material to
be cyanotyped is prepared by the students in advance
and allowed to dry. After a few hours, students can
place objects on the material and then expose it to
sunlight or UV light. Once the UV light hits the cloth
or paper, a light-activated redox reaction occurs. Areas
that are exposed to the light turn blue, while areas
not exposed stay unchanged. Then, simply rinse the
material under water and a white imprint of the object
is created on a dark blue background. Developed in
conjunction with Linda Stemer, this kit can be adapted
for use from 1st graders through 12th graders. Includes
materials for a class of 30 students. Note: White cotton
T-shirts are not provided in the kit, however, you can
conduct the experiment using your own in place of
the provided cotton cloth.
