                                Experiment 1: What you will need: 1.Balloon 2.Your hair or silk or warm  cloth 3.place near wall What to do: 1.Take the balloon and rub it with your hair as quickly as possible. 2.make it closer to the wall 3.you will see that it sticks with the wall. How it works: *When you rub the balloon with your hair it produces static charge in the balloon which is a negative and when it get closer to the wall it sticks because the wall have + charge and the balloon- the two opposite charge attract each other resulting the balloon to stick. For best results try on a cold day with less humidity. Experiment no.2 What you need: 1.A plastic scale(or comb). 2.A piece of paper. 3.A scissor . What to do: 1.Take the piece of paper and  tear in into small pieces with the scissor. 2.Place the small pieces of paper on a surface. 3.Now rub your scale with your hair for  10 to 15 ...
