A black and white image of a rabbit takes on full color. This is done with a change bag, dye box, dye tube, cabby box or any device that will change a silk. Show change bag empty. Put the black and white silk in the change bag with a few crayons or take imaginary colors off the kids clothing and add them to the bag. Produce the color silk of the rabbit and show the bag empty again. Silks measure approximately 16 inches square.
