A fine example of teaching-through-print and pictures, the book features 125 step-by-step illustrations on the hows and whys of space flight. Based on material that the author wrote to accompany a filmstrip produced for the D. C. Heath Co., pictures and text have a clear presentation quality and combine to make a book that should be welcomed by science teachers. The suggested experiments are designed to answer questions about the principles of rocketry, weightlessness and direction in space (among the many other intriguing concepts covered) and are blessedly simple to follow. The equipment employed for these are from the kitchen and the toybox -- marbles, ping-pong balls, paper, candles, pots and pans, etc. The illustrations (many in full color) are big, clear and well labeled.
