KIRKUS REVIEW

The basic design and just enough advice on materials and construction to get self-starters going on their own ""scientific toys""--from a simple periscope and thaumatrope to speaking tubes and bull-roarers, a radiometer (a good deal simpler than Danny Dunn's, see above), water and mercury barometers, a crystal garden and a pair of ""electrical boxers"" run by static electricity. The concepts are straightforward. The execution is another matter; some of these toys are simple, others take a good deal of skill and patience, and perhaps some grown-up help in the clinches.
