Step 1: Rub a balloon briskly across your hair, then hold the balloon over the bits of paper Step 1 Observation: The balloon attracted Stanton’s hair (the negatively charged electrons were tranfered to the baloon, attracting the postive protons in Stanton’s hair) Step 2: Hold the balloon over little bits of paper. Step 2 Obseravtion: […]
