Sitting outdoors with eyes turned upward to the sky to watch fireworks has been an integral part of celebrations for hundreds of years. From national holidays to birthdays, people have been enjoying these colorful displays for generations. With advances in science, the realm of pyrotechnics is expanding with new and exciting innovations. Electronic Firing Old methods of setting off fireworks involved the pyro-technician lighting each fuse manually to set it off. This method was slow, and it was impossible to time the launch to choreograph it with music. Newer launch technology involves a delay fuse inside the launch tube. After launch of the shell into space, the delay fuse causes a pause until the shell reaches the desired height. The delay fuse can also be connected to a computer standing by to signal the precise time for ignition. Then the pellets inside the tube explode for a brilliant display. Choreography with Music The trend of setting off fireworks in conjunction with music is popular with many viewers. With the lack of precision in launching displays in the past, this choreography was never possible. Now with the intricate timing of computer-enabled electric matches, event planners can design a show with timing as precise as the millisecond. This enables the explosions of color to happen at the exact second necessary to maintain connection with a musical rhythm. Shapes and Letters Patterns and designs are becoming more complex as they explode in the sky. The pellets inside the shells can be arranged into different patterns to produce various shapes and designs, including circles, stars, and hearts. For many of these shapes, it's important that they be oriented in a specific way to produce the correct display. For example, an upside-down heart would not be optimal in a festive show. It's also possible to produce letters in a display. However, the possibility of error with the orientation of the pellets in the shells is somewhat high. For this reason, many pyro-technicians opt not to attempt these specialty displays yet, waiting for more technological advances to occur that will make the shows less problematic. Advances in Color Bigger and brighter colors are another result of advancing science. Pyro-technicians have learned about the chemical properties of various elements that result in specific colors at high temperatures. Electrons react to heat. When they begin to cool, the resulting energy gives off more light that appears as various colors. The colors produced depend on the specific chemical involved. For example, sodium produces a brilliant orangish-yellow color. Magnesium and aluminum result in expansive explosions of light that appear white in color. Barium results in a glittering green. In general, the hotter the initial explosion, the more brilliant the colors will appear with gradual cooling. Technicians still struggle producing blue hues, however, due to the fragility of these atoms. As research and technology march onward, fireworks displays should continue to become bigger and more impressive with brighter colors and more intricate designs. Prepare to be awed and amazed at outdoor celebrations and festivals. When looking for fireworks, Poconos, PA shoppers go to http://thefireworkssuperstore.com.
