Lightining Bolts

Lightning is nothing more than a broad spark created when negatrons cleft out between clouds or between the earth and the clouds. The standard atmosphere is eer in a state of galvanic eruption. normally the atmospheric galvanic charge is harmless. It is only when very bad clouds take and they produce intense rain that a huge (and dangerous) electrical charge accumulates in the clouds. The accumulated atmospheric charge undergoes and electron avalanche which manifests itself as lightning. Inflate three billows, colour ar optional. Attach all(prenominal) amplify to a silk or nylon (electrically insulating) thread, individually about 1.5m long. The three loose ends should be attached to the schoolroom ceiling at a single point. In their drained state the balloons impart hang more or les right away down. Charging Rub each balloon vigorously with a pick of fur to give it an electrical charge. Once each balloon has been charged turn they forget rep el each other. This get out cause them to separate at the ends of their support strings as shown in the figure to the left. If the air in the classroom is ironical the balloons allow remain charged for several minutes or more. The reflexion (part 1) Bring a metal rod with a conductive ball one up to the cluster of balloons. An aluminum or copper rod with a discarded ingress knob attached to the end works well.

The cluster of balloons has a positive charge. The metal rod held in your hand is a virtually infinite source of negative charges. Little offer will be noted in the configuration of the balloons. The introduction (part 2) Turn the rod ! around and put the pointed end in the same position as before. Now the cluster of balloons will fall together dramatically. When the rod is removed the balloons will former(prenominal) again separate. Repeat the procedure several times. -------------------------------------------------------------------------------- For reasons involving electrostatic forces, electrical charges tend...If you want to get a full essay, order it on our website: OrderCustomPaper.com
