Van De Graaff Generator

Today we went up to the science to test the Van De Graaff Generator, it runs static electricity that each student got to be conductor and experience the shock. The first demonstration was the single touch, Alex's hair stood up straight since the electron are repelling each other and taking space in the hair. By receiving electrons going throughout your body the person now have more negative charge therefore repelling the space and the hair extends up caused by the conflict force.



During most of the experiments, plastic was stood on to prevent grounding, plainly stepping on the ground causes a stronger shock since the electrons now have the earth as a destination point for grounding. On the other hand passing on static electricity in a chain reaction become ineffective since electrons always take the shortest passage.



Touching metallic object when receiving electron in your body can result in a tremendous shock visible to the human eye. When the last people in the chain touch the water it bends and touching the metal sink causes the much greater shock. The water bend towards the electron charged "conductor" because it's neutral, the positive proton in the water attracts with it.
