Thaumatrope (Magic Circle)

The thaumatrope consists of a circle of cardstock, 2.5 inches in diameter with 2 strings attached, one each at opposite points of the diameter. There were 2 images painted on the cardstock, one on each side, with their positions inverted. The outline of the image was usually printed and the color hand-painted in (Barnes 7).

Magic Lantern Slides 2

According to Charles Musser, Huygens had two key innovations for his magic lantern: 1. Images painted on glass instead of etchings on mirrors. 2. An artificial light source was used instead of the reflection of sunlight. (20) Glass slides (often more than one) with hand drawn images are the standard aesthetic for these slides. They are then usually mounted in rectangular wooden frames approx. 4 x 7 inches with a 3 inch circular opening for the image. (Musser 30) The various mechanisms attached to the images are described in the Object Narrative section.

Modeling of Magic Water Clusters(H20)2 and (H20)21H+ with the PM3 Quantum-Mechanical Method

The PM3 quantum-mechanical method is able to model the magic water clusters (H20),, and (H20)&+. Results indicate that the H30+ ion is tightly bound within the (H20),, cluster by multiple hydrogen bonds, causing deformation to the symmetric (HzO),, pentagonal dodecahedron structure. The structures, energetics, and hydrogen bond patterns of six local minima (H20)21H+ clusters are presented.
