: S INVISIBLE COLOR BOOK BUBBLE CASTLES HERE was a tiny brook where Zenna-Mae liked to play, and she went there often in the long summer days with her dollie. In the brook Tthere was a little waterfall that went bubbling over the rocks and trickled past where she would sit. Today she noticed the bubbles floating along on the water, and dancing up in the spray. She wondered what they would look like if she could see them close and big. A Gnome appeared who said he could read her thouchts, and told her he was in charge of all the bubbles to keep them from breaking so she could see them. Look what he did to the little waterfall and the bubbles after he read the thoughts of Zenna-Mae. With a brush and plain water paint the bubbles and see the colors in them.
