The writer hopes that no student will design a science project that is supposed to create laser Italian charms. The writer does not encourage students to search for a laser, in hopes of making some laser Italian charms. Instead, the writer suggests that students study the information below about the creation of a statically charged object. The writer shared that information with her own son. Her son then used that information to make a science project for his 8th grade science class. He did not make use of either a laser beam or an Italian charm in that simple science project.
What characteristic does each of the laser Italian charms share with a plastic spoon? Both the laser Italian charm and the plastic spoon have an insulated surface. Therefore, both objects can be given a static charge.
The enamel coating on an Italian charm can be charged by the touch of a laser. A plastic spoon becomes charged when rubbed with a piece of wool. Innovative thinkers have shown how those two charged surfaces can perform two special functions.
A statically charged plastic spoon has the ability to pick up grains of pepper. It is, however, too weak to pick up grains of salt. For that reason, a charged plastic spoon can be used to separate a mixture of salt and pepper.
What about the charge created on one of the laser Italian charms, how can that charge perform a useful function? The charged enamel on an Italian charm becomes the surface on which the skilled jeweler works. The jeweler focuses the point of a laser on that enamel surface. The laser point acts much like a paint brush.
A simple metal charm can not take on a static charge. Yet once that metal surface becomes covered with enamel, it becomes an insulated surface. Exposed to the proper substance, that enamel surface becomes charged. A laser beam can then perform pin-point changes on that charged surface.
The jewelers who make the laser Italian charms use a laser beam emitted by a corona wire. The corona wire scans the enamel surface on the charm. Using information from that scan, the jeweler focuses the laser beam at specific points on the charm’s enamel surface. The touch of the laser changes the charge at a single point on the enamel coating.
When one point on the enamel surface takes on a charge opposite to the adjacent charges, it becomes attracted to those opposing charges. In that way, the touch of a laser beam can be used to remove a single point of enamel. A skillful jeweler can use a laser beam to create a pattern of electrical charges. That pattern of electrical charges produces an image on the laser touched charm.
Still, one must realize that not all of the laser Italian charms have an enamel surface. Besides having the ability to change a static charge, a laser beam can also put tiny indentations in a metal surface. A laser beam can thus be used to engrave either words or a drawing on that metal surface.
Laser Italian charms illustrate the pervasive nature of computer technology. The jeweler relies on a computer program to tell him or her where to touch a laser to a particular Italian charm. The computer program guides the skilled hand of the jeweler, leading to the production of many beautiful Italian charms.
