Experiment with water sample that brought to boil
I attached the cut-out picture of dolphin to the jar filled up with ordinary tap water. I kept it on the window ledge for a while and then brought to boil in the pan covered by photo paper, instead of lid. I left the photo paper on the top of the pan from the very beginning of the experimental boiling and for 5 minutes after the water started boiling. The steam was penetrating the paper. After that I applied on the processed paper a tint of sunflower oil and left for a few minutes. When the oil gone through the photo paper, I put the picture against the window glass and photographed it. This is what I‘v got:For the picture below I used just a sample of water in a clear jar. I extracted 20 ml of the water sample and placed it on the top of the photo paper (other side of the photo paper),while the rest of the water was boiling underneath it. See the pictures of two different samples of water below:
However, there is a positive thing! The area of the paper penetrated by boiling water is not absorbing the oil applied immediately after the experimental boiling. So, it gives the picture of the evaporated water that gone through the paper.
I took the video of the boiling water with added colouring to see how the colour spreads over. See the video below:
