With this kit, children can make a real radio, a spinning motor, a light flashing generator and a clicking telegraph. Summer camps and boy scout troops have repeatedly used Inventions in their programs. This kit has received many national awards. The projects actually work, even in large groups where individualized attention is not possible. This kit has been used at MIT to mentor high school students in physics, and has been used at the Fermi Lab and the University of Texas at Austin.
