Pinch and Mix Goo (www.stevespangler.com)
Ziptop plastic bag (quart size works best)
Squirt one or two tablespoons of each color goo into the zipper-lock bag. Put one color in each bottom corner and the third color in the bottom middle of the bag.Take care to gently squeeze as much air out of the bag as possible before sealing it. Then pinch and mix the goo with your fingers.
The colors begin to blend from primary to secondary colors! The blue and yellow are becoming green, the red and yellow are turning orange, and the red and blue are blending into purple! Soon your bag will take on a soft, stained-glass effect. What fun!
