Lightining Bolts

Lightning is nothing more than a capacious spark created when negatrons cracking out between clouds or between the earth and the clouds. The ambiance is eer in a state of galvanic indicate. normally the atmospheric galvanizing charge is harmless. It is only when very declamatory 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, act upon ar optional. Attach all(prenominal) billow to a silk or nylon (electrically insulating) thread, each about 1.5m long. The three loose ends should be attached to the classroom ceiling at a single point. In their uncharged state the balloons impart hang more or les right off down. Charging Rub each balloon vigorously with a overcharge of fur to give it an electrical charge. Once each balloon has been charged turn they forget r epel 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 modify the balloons volition 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 aluminium or copper rod with a discarded entrée 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 serve will be noted in the configurati on of the balloons. The demo (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 quondam(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: BestEssayCheap.com
