The Magic Fact Machine: Science: Gives the Right Answer Every Time

Two titles by Jay Young point the way to higher learning. On each spread of The Magic Fact Machine: Science and The Magic Fact Machine: Animals, readers press a pointing robot finger into a hole on the left, then turn it so that it points at a question (e.g., ""What is unusual about the metal mercury?""). When they place it in the hole on the next page, the finger magically spins toward the correct answer (""It is liquid at room temperature""). Full-color photographs and brief blocks of text explain the overriding issues. ( Sept.)
