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.

Will this paper work under ordinary light if it rains on the day we plan to use it?

The paper will still change on a cloudy day. I would recommend leaving it out a little longer. Just be aware the image may not be as vibrant as it would be on a sunny day. It’s a great way to show out UV rays (the bad rays we have to protect ourselves from) still get through on a cloudy day.

Autumn –
Will the paper change color in regular light. For example when I am doing my experiment, and putting my sunscreen on the paper will it start changing color before I have a chance to put it under the sun?

Autumn – thanks for the question. The Sun Sensitive Paper can be used with Sunlight or with Black Light. I would suggest if you want to use sunscreen as a variable I would recommend to put the paper in a zip lock bag and apply the sunscreen to the bag and not directly to the paper. Applying sunscreen to the paper will only saturate the paper. Please let us know if you have any questions and we’ll be glad to discuss – Joshua – 800-223-9080

Nicole –
I was wondering if you could use this paper indoors with a UV flashlight? If we suspend the UV flashlight over the object on the paper, would we be able to see a difference between the outdoor UV rays and the UV flashlight?

Nicole,
Thanks for the e-mail. As long as the sun sensitive paper receives UV light it will work. I would suggest getting the UV Flashlight fairly close to the paper to get the best results. I would suggest a few inches from the paper. Follow the instructions as you would if you did it outside with full sunlight. Please reach out to us if you have any additional questions. Have a great upcoming weekend. Joshua

Dominique – I would suggest using printer paper for this experiment. The Sun Sensitive Paper is great for outdoor use but does take at least 15 minutes to shadow out a design. Great Question. Josh

James Nderu –
My students got that idea that water stops the process and fixes your images on the paper. Our concern is what makes the colours to interchange, i.e where we had an object block the sunlight turned remain blue and the rest of the paper turned white. When dipped in water to stop the process, the colours interchanged, Why?

The paper is made in the United States and is perfectly safe to use with young children.

Sam –
Hi, I just wanted to know if I could test the effects of sunscreens (sunblocks) with the sun sensitive papers.
i.e. If I apply sunscreen to the sun sensitive papers, will that spot remain white whilst the other spots turn blue? And will this show the effect of the sunscreen, blocking the UV light?
Thank you.

You can test sunscreen using the Sun Sensitive Paper. I recommend laying a piece of cellophane on top of the paper first so the sunscreen does not seep through and ruin the paper. The paper will still change color even when using the strongest SPF, showing that some UV rays still come through. You should see a difference in shading, though, between the strongest SPF versus the lowest SPF.

Is it possible to use this paper and test a variety of alternatives to sunscreen to see which is stronger?

You can test sunscreen. Be sure to lay down some cellophane to protect the paper. Otherwise, the sunscreen will seep through and possibly ruin the paper.
The paper will change color even with the strongest SPF lotion. It’s a great example of how UV rays can still sneak through and how well we need to protect your skin. You will see a difference in shading between the different levels of SPF, though.

kelly –
Is it possible to use this paper to determine the amount of light the paper has been exposed to over time? I want to place a sheet in a spot for a plant to determine if the plant gets enough light exposure. If I placed a sheet in the spot for 8 hrs could I tell by how blue it turns as to how much sun it received?

Unfortunately, the paper would not work for this type of experimentation. I would contact a garden store and I bet they would have some great suggestions for you in determining how much light an area gets.

If you don’t put the paper in water, is it possible to reuse it and do other images?
(1) (0) Watch Unwatch
Staff lisabrooks –
The Sun Sensitive Paper will react in the same way as the old film we used to use. Once it is exposed to light, the “film” will be used. Running it under water just completes the development process so the image will come through. If you did not complete the process of running it under water, it would eventually just turn very dark or black.

Hi, is it possible to increase the size of the paper by any chance?

The Sun Sensitive Paper comes prepackaged. You could always tape pieces of paper together to do a larger image.

Can i split the package into smaller kits to give to kids without exposing the paper to light?

Lisa – Customer Service Manager –
You could split up the package amongst your students. I would recommend opening the pouch in a room with little sunlight to avoid exposure. To divide them up into smaller kits, you would just need to make sure you have some sort of packaging that blocks the light.
