Lightining Bolts

Lightning is nothing more than a coarse spark created when negatrons sallying forth out between clouds or between the earth and the clouds. The breeze is eer in a state of galvanic wedge. ordinarily the atmospheric galvanic charge is harmless. It is only when very immense 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) balloon to a silk or nylon (electrically insulating) thread, each(prenominal) about 1.5m long. The three loose ends should be attached to the schoolroom ceiling at a single point. In their neutral state the balloons impart hang more or les at present down. Charging Rub each balloon vigorously with a reject of fur to give it an electrical charge. Once each balloon has been charged turn they forg et repel each other. This provide 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 teetotal the balloons will 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 incoming 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 whirl will be noted in the configuration of the balloons. The materialisation (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 erstwhile(prenominal) again separate. Repeat the procedure several times. -------------------------------------------------------- ------------------------ For reasons inv! olving electrostatic forces, electrical charges tend...If you want to get a full essay, order it on our website: BestEssayCheap.com
