Water Soluble Markers
I now wish I had posted this sooner to remind myself whether this is from watercolors (some of which contain sparkly flakes) or extracted ink from water soluble markers. There may or may not be a golden confetti treasure inside as well. The effect was remarkable, showing green and/or red when rotated and viewed with the sun located behind it. Any comments as to the reasons behind this effect would be greatly appreciated!
A water solubility experiment. Crayons and water based markers on wet paper.
Provide open-ended materials for experimentation by the students.
Eye catching: water in beakers with plants parts and colored cellophane catches the light.
