Many projects are of contemporary interest—magic, kites and boomerangs for example. Try a ["Querl"] for starters.
There are many projects of purely historical interest, such as chemical photography, phonographs, and devices for coal furnaces.
Another class of projects illustrate the caviler attitude toward environment and health in 1913. These projects involve items such as asbestos, gunpowder, acetylene, hydrogen, lead, mercury, sulfuric acid, nitric acid, cadmium, potassium sulfate, potassium cyanide, potassium ferrocyanide, copper sulfate, and hydrochloric acid. Many references to these have been highlighted in red.
Projects requiring extra skill and care that involve high voltage, melting metals, or other hazards, have the title highlighted.
Please view these as snapshots of culture and attitude, not as suggestions for contemporary activity.
Be careful and have fun, or simply read and enjoy a trip into yesterday.]
