Product Description

Make amazing white on blue prints with your favorite objects! Just place leaves, flowers, shells or whatever you choose on the photo-sensitive paper and place in the sun. Remove the objects after a couple of minutes and rinse the paper to “fix” it. Congratulations, you’ve made a permanent piece of sun art!

Recommended for children ages 6 and up.

What’s Included?

30 sheets of 12.70 cm x 17.78 cm (5″ X 7″) sun sensitive paper

How Does It Work?

The nature print paper is coated with light-sensitive chemicals, which react to light waves and particles when exposed to light. When you place objects on the paper, they block the light and turn white while the paper around them remains blue. Water stops the process and fixes your images on the paper.

What Does It Teach?

Learn about the nature of sunlight and how light-sensitive chemicals work. From here, launch a discussion about how color photos are developed, as each layer of chemicals on the film react to photons of different color.

Science Fair Connection:

When the Sun Sensitive Paper reacts to ultraviolet light, it’s a pretty fantastic demonstration of UV-reactive materials. However, this awesome demonstration isn’t, by itself, a science fair project. To create a science fair project using the Sun Sensitive Paper, all you need to do is identify and use a variable. A variable is an aspect or factor of the experiment that you can control and alter. Here are some examples of variables that you could use:

Test different sunscreen brands or SPFs by spreading the sunscreen on the paper.
Try to find the best pair of UV-blocking sunglasses.

Once you identify your variable (don’t let us hold you back, if you have better ideas, use those!), start conducting your experiments. Make sure that you keep all other factors the same, though. Otherwise, you’ll have multiple variables!

Frequently Asked Questions

Can you explain how I “set” the image?

It is really easy to set any image, all you have to do is place it on the sheet by itself. If you were to use tape on the edges, then the tape would leave its imprint on your image as well.

What types of objects work best?

Any object will work as long as it blocks the sun. Objects that are semi-permeable or ones that don’t lie flat against the paper may let some light through to cause the developed image to be less defined.

What size is the paper?

You get 30 sheets that measure 5 1/2” by 7 1/2”, which is just the perfect size for your class.

How long does it take to work?

It works best if you leave the image in the sun for about 2 minutes and then bring it in without allowing the covered part the be exposed to sunlight. Let the paper sit in some water for about a minute and then your image should be ready to displayed.
