  3. Slowly add the cold water and stir
  4. Heat until it thickens and turns clear, stirring constantly
  5. Cool
  6. Divide into the three bowls and add one color of food coloring to each bowl, and stir.  Add as much food coloring as needed to achieve desired intensity
  7. Add half of each of the three colors into each ziploc bag, making sure to keep the colors separate at this point

  9. Now it’s time to play, discover and investigate!  Two bags allows adult and child to investigate together.
  10. What colors can you make?  Can you make a whole rainbow?

  12. If you want to save it to play with another day, keep it in the fridge so that it won’t spoil.
