The Rainbow Connection
by Amy on June 14th, 2016

​​We wanted to add a little something extra to some of our weekly park days this summer. The "extra" wasn't defined very precisely, but we'd talked about a craft or a science project that the kids would enjoy and maybe learn a little something new. Sorting through my sadly neglected Pinterest account, I decided on a project that was both a little crafty and a little science-y: Rainbow Paper. The set up is pretty simple, which was perfect for transporting to the park.  

Materials Needed

  • ​cake pan, filled halfway with water
  • black construction paper
  • clear nail polish


  1. Press a sheet of black paper into the water until it is fully submerged
  2. Add a drop or two of nail polish.
  3. Immediately lift paper out of water through the polish.
  4. Tilt paper into the sunlight to see a rainbow of colors.
  5. Scoop any remaining dried polish out of the water before making another.

How It Works

​​When you remove it from the water, the paper becomes covered with a thin layer of nail polish. Like droplets of water that form a rainbow in the sky, the polish disrupts light waves, bending white light into all the colors from which it is made up. Want to learn more? Visit
