Great nature project with the grandkids

I let my sun print paper sit in the sun for 5 minutes. Then, I rinsed my sun print in water and let it dry. It turned out as expected.

This paper is not. Good quality at all. Disappointing

This is a disappointing product. I does not result in the deep blue pictured.

These are either a different product than shown in the video or mine were 100% defective. All of the ones I got do NOT work with water, it completely washes off whatever chemical is on the paper. It works well enough without doing the water step but they don’t get very blue. Bummer
