Cut a slit from the edge to the center of each colored disk. Glue the cardboard circle to the top of the spool. When the glue has dried you can slide the disks on top of the spindle. If you overlap the slits on the colored disks, you will be able to make up different proportions of color. By spinning the top quickly the colors on the disks will combine with one another and blend into a single color. Newton’s Rings Have you ever noticed the rings of color floating in a patch of oil-covered water in a puddle on the road?
The two pictures should merge into one because of the principle of the persistence of vision. Moving-Picture Machine The stroboscope is a device that was invented in 1832 by the Belgian physicist J. A. F. Plateau. It is a simple device that allows motion to be slowed so that a moving object appears either slower than it actually is or stationary. The phantascope is a variation of the stroboscope and makes it possible to observe sequential pictures as though they are actually moving. The discovery of the phantascope is often credited to the Austrian geologist S.
Glue one onto each side of the cardboard. Be sure that the drawings are directly opposite each other and upside-down relative to each other.
