Como fazer uma MÁQUINA DE CHOQUES caseira para FEIRA DE CIÊNCIAS - Summary

Summary

The video demonstrates how to create a homemade shock machine that doesn't require a battery or electricity. The machine is assembled using a pot with an insulating lid, a piece of wire or a nail, a ping pong ball, a piece of aluminum foil, and a small amount of static electricity. The static electricity is generated by rubbing a balloon or PVC pipe with clean, dry hair or with a tube TV or CRT monitor. Once the machine is assembled and charged, it can be used to give a mild shock by touching the aluminum part with one hand and the ball with the other. The machine doesn't pose a danger if used properly, but it could become dangerous if charged with a professional static energy generating machine like a Van de Graaff generator. The video concludes with a warning that children should not attempt this at home and that the experiment works best in dry weather.

Facts

1. The video demonstrates how to create a shock machine at home without needing a plug or battery.
2. The first requirement is a pot with an insulating lid, preferably made of plastic.
3. A small piece of material that conducts electricity is needed, such as a piece of wire or a nail.
4. Two pieces of thread and a ping pong ball are also required. If these are not available, a Rolon deodorant can be used.
5. A strip of aluminum foil is needed, which should be smaller than the height of the pot.
6. The aluminum foil is used to cover the inside and outside of the pot.
7. A metallic lollipop is made using the ping pong ball and the piece of wire.
8. The lollipop is then placed on top of the pot.
9. The machine needs to be charged by generating static electricity.
10. Static electricity can be generated using a balloon or a PVC pipe.
11. The machine can also be charged by rubbing the PVC pipe on a paper towel.
12. The machine can be tested by touching the aluminum foil to the ball, which should cause a spark.
13. The machine can be charged by turning a tube TV or a CRT monitor on and off several times.
14. The machine can be charged using a professional static energy generating machine, such as a Van de Graaff generator.
15. The machine works as a capacitor, an electronic component capable of storing electrical charges.
16. The machine is named a Leyden jar or Leyden bottle, a classic experiment in physics.
17. The machine can be tested by touching the aluminum foil to the ball, which should cause a spark.
18. The machine can be charged by rubbing a balloon on your hair and then rubbing the balloon over the metal ball.
19. The machine can be charged by rubbing a PVC pipe on a paper towel and then passing the pipe over the machine.
20. The machine can be charged by turning a tube TV or a CRT monitor on and off several times.
21. The machine can be charged using a professional static energy generating machine, such as a Van de Graaff generator.
22. The machine works as a capacitor, an electronic component capable of storing electrical charges.
23. The machine is named a Leyden jar or Leyden bottle, a classic experiment in physics.
24. The machine can be tested by touching the aluminum foil to the ball, which should cause a spark.
