Technology – Post #3

In technology yesterday, we did an experiment about how effluvia (static electricity) moves a piece of tinfoil inside a jar. In the experiment, we rubbed a plastic stick on wool. This transferred the electrons from the wool to the plastic. Then you take the stick, and put it close to the rod attached to the tinfoil. Since the rod was also filled with electrons, the electrons in rod went to the tinfoil, since electrons don’t like each other. Then the tinfoil moved because the electrons were trying to get away from each other. Overall, I really liked this experiment!
