- A form of energy resulting from the existence of charged particles,such as electrons or protons.
This experiment with electricity, mainly static, is very cool and simple to complete. The creator demonstrates electrical principles as it relates to electro magnetism. The aluminum foil is used as a conductor to harness static electricity left over from a television. In simple terms the cans are charged with free electrons that causes a magnetic field. The results are a positive and negative difference on either side of the can as well as the tab. These charged differences force the tab to swing.
Conclusion: This small amount of static electricity can be harnessed to do work.
Interesting Fact: Thomas Edison was not the first person to create the light bulb. In 1874 Canadians Henry Woodward and Matthew Evans placed a thin metal rod inside a glass bulb. They removed the air out of the bulb and replaced it with nitrogen gas. A electrical current was passed through it, creating the first electric lamp. Due to lack of financing, Woodward and Evans could not pursue further development. In 1889 the duo sold their patent to Thomas Edison.
Note to Parents and students: Please use extra caution when attempting this experiment. Students do not try this experiment without your parents supervision. Parents keep a watchful eye over your little ones (or bigger ones). Static electricity is considered high voltage but it doesn’t have the amps (the kick) to do much harm outside of a little jolt. Have fun but safety first!
