The article describes an experiment involving a solid ball resting in a smooth sheet of paper. Topics discussed include the behavior of the ball being independent on the acceleration of the paper as well several different paper removal speeds being investigated experimentally. Also mentioned are calculations involving ball rolling without slipping and ball rolling with slipping.

The article discusses several ways on how to make capacitors from common materials. The materials used include a roll of aluminum foil, sheets of paper, and a book. The types of capacitors that were created and discussed include parallel plate capacitor, radial electrolytic capacitor, and two-plate book capacitor.

The article contains experiment to demonstrate fluorescent emission spectra of neon colored papers and plastic clipboards. The findings indicate that the shorter wavelength light is utilized by the “Daylight" pigment contained in these neon papers to enhance the reflected light in the longer wavelength regions thus making them appear brighter.

The article presenst a method for measuring the refractive index of liquids that can be used as a class experiment or teacher demonstration. It mentions that an open rectangular container with thin transparent walls, an opaque strips 3-4 cm wide, and a sheet of paper are among the materials needed. It states that adjustment of the strength of the source, the distance of the source from the opaque strip, and the width of the container will lead in optimally sharp shadows.
