Electric forces(BP#2)

I always wondered why no matter how long I dragged my feet on a rug I could not shock anyone. I The reason is because we live in Hawaii we are surrounded by water and there is a lot of moisture in the air which pulls away charge from charged things. In class we got to play around with an apparatus that statically charged a metal ball. The charge was from static electricity caused by friction. This picture above shows another form of static electricity caused by rubbing a balloon on someones hair. The balloon becomes charged as well as the persons hair and they attract each other. This is sort of like the machine that we had in class except the machine produced a lot more energy and we could get shocked from it. This is because our bodies have a charge but not as much as the metal ball produced so when we come close or become in contact with it the reason we get shocked is because its like charges evenly distributing it self among us and the ball. If we leave or hand on it the charge distributes and becomes even and we don't get shocked. If that person touches something or someone else the same thing would happen to him and the person because he holds the charge of the ball. Electricity can be transferred to one another or anything that conducts electricity. The difference in charge of the two objects( hand and metal ball) determines the strength of the force pulling the two charges together. The greater the charge the greater the force. Overall we learned how a simple thing from the balloon and hair trick is the same thing as the apparatus being charged by friction just on a bigger scale.
