Sample text

The sugar will make it possible to blow larger bubbles. Blow a soap bubble. At first, while its diameter is still small, the film will be colorless and transparent. However, as you blow more air into the bubble and its diameter increases, the film will become thinner. As the soap bubble increases in tenuity, a brilliant series of rings of color can be seen on its surface. When you release the bubble and it floats through the air its colors will become iridescent. Distorted Images Have you ever seen yourself distorted into weird forms and shapes by the concave and convex mirrors at a circus or amusement park?

Try finding shiny objects with concave surfaces that you can use to observe a variation of this optical phenomenon. How do concave surfaces distort images of objects? 4. Static Electricity Detecting Static Electrical Charges In 1600 Dr. William Gilbert (1540-1603), an English physician, published a book on his observations and discoveries about magnets. The book also contained a description and illustration of the first electrical instrument in history, known as the “versorium” (which means “thing used for turning”).

Fill the glass full of water. Place the sheet of paper over the top of the glass. Hold the piece of paper in place over the top of the glass with one hand. Turn the glass upside down with the other hand. As you move the glass closer to the surface of a table, desk or countertop, remove your hand from the piece of paper, and place the glass on the table. Then, carefully lift the glass just enough to quickly slip the piece of paper out from under the glass. Air pressure will hold the water in the glass even as you lift it slightly to remove the piece of paper.
