Rainbow in a Bag

Mix in a pot….

 

1 cup cornstarch

1/3-cup sugar

4 cups cold water

 

Heat stirring constantly. Once it starts to thicken – remove from heat – it will resemble wall paper paste initially but as it cools, is more like Vaseline. Divide between as many bowls as you have colors (food coloring). Add some food coloring to each bowl and mix. I chose primary colors only.

 

When it has cooled (I couldn’t wait that long), scoop some of 2 or more of your goop into a ziploc bag (or similar – my eco conscience was able to justify using the bags as it’s in the interest of education!).

Seal the bag and squish and squeeze to blend the colors – hold bags up to light (window in our case) to see the results in its full coolness.
