Great stuff! "How to Perform Entertaining and Instructive Experiments with Simple Home-made Apparatus". To name a few: Hydraulic Ram pump, Static powered electric motor, electromagnetic gun, levitating pea, high frequency alternating currents,decomposition of steam with and induction coil, homemade "cheap" X-ray machine using a light bulb, and an induction coil. Although some of these experiments are 100 years old, and may not be safe, we believe them to be more valuable and better for mind than most new video games, and they come at a fraction of the cost!
