Harry Houdini's copy of Scientific Amusements left by his estate to the Library of Congress in 1927. From the Preface:
Young people of both sexes, and persons of all ages who have leisure and a taste for that which is ingenious as well as instructive and amusing, may be commended to this remarkably interesting collection of experiments, nearly all of which can be readily performed by an unskilled person who will carefully follow out the directions given. It is surprising how near we are to the most fundamental principles of science when we perform some of the simplest operations.
