If you had made a title and thread about Franklin's lightning bells that would have been interesting.
But what you have done instead is made a thread titled "Home Wether "Radar"". There are a number of issues with this:
1. It's not a weather device. Where I live it rains every year yet most years I don't get any lightning.
2. You link to a source about Franklin's bells, but the image you show is of balls, not bells, and it wouldn't work like Franklin's bells.
3. While it's probably possible to design a much more effective experiment, maybe attempting to duplicate Franklin's bells using bells, it's far too
dangerous for most of us to do so, as your warning suggests, however I'm not sure your warning is adequate. If lightning strikes the plasma arc
doesn't need any wire so I'm not even sure what you mean by "with the copper wires attached to a nail , so as to be capable of disconnecting." You
would also need to have a professional electrician check any lightning rod wiring and even then it's still possible you could have problems when
lightning strikes. My warning would say "don't play with lighting rods at home, it's too dangerous".
4. Lightning comes in groups so the best, easiest and safest way to see where lightning is active is to look at a live lightning map:
We live in an age of amazing technology.
If you want to duplicate the Franklin Bells experiment, this source has a much better idea, use a high voltage power supply rather than a lightning
These sparks could very dangerous and a direct strike to the lightning rod could cause explosions and fire. A safer version of this experiment is
easy to setup by using a simulated lightning rod in the form of a high voltage DC power supply such as a Van De Graff generator or Voltage
If you don't have some bells available then they can be replaced by any metal object such as a drinks can. This experiment works best if all the
conductors are smooth, but a foil coated plastic ball will be ok if another type of lightweight metal ball is not available.
That points out some
other problems with your idea, you showed heavy balls and you need a light ball like a foil coated plastic ball, and you also need some bells if you
want bells to ring.
Conducting the experiment with a High voltage DC power supply instead of a lightning rod would be a lot safer, since you no longer have the risks of
actual lighting strikes, but you still have a risk of electrocution if you're not careful.
