A satisfying hands-on experience using the three primary colors to create secondary colors.
Pre-fill bottles with red, blue, and yellow food coloring/water solutions. Children place one dropperful of red and one dropperful of yellow in a small bowl—like magic, orange appears! Repeat this procedure with blue and yellow (green), and red and blue (violet).
Children can use the fourth bowl for experimenting. When finished, empty all the bowls into the larger bowl and empty it into the sink. Ages 4+.
