This book by Laurence B. White, Jr. contains approximately 49 scientifically based toys and tricks that children can do. Several of the selections can also be used as the basis of school science projects.
A paper flower that blooms in a glass of water.
A ghost that sticks to the wall when you rub it.
A balloon dog that rolls on his back at your command.
They are all toys and tricks but they are a special kind. Science makes them work.
