【A pendulum which is moved by static electricity】Ⅱ

We put on a glove made of rubaer and grasp the third empty can with a hand of glove.We bind the can with a wrap.😃

By the way,I misunderstood.We don't have to a pair of gloves. Either of them is all right.😳

We get rid of the wrap from the can all at once. The can gives off the static electricity.We hold the can which gives off the static electricity, and bring it up to one of another cans which are on the styrofoam plate.Then the thumbtack begins to swing so much.😲

When the pendulum of the thumbtack doesn't swing very much, we only have to bring up to one of the cans through which the straw is passed to another one.🙋

To be continued.By😁
