I'm really sorry to you all, I only watched half the video. Here is the link: In the end he tells that all this is fake and he has been hiding his tesla coil under the table. Really sorry for wasting your time. Sorry @studiot @Intoscience and @iNow

If you learned something it's not a waste.

Thank you guys, appreciate your efforts.

You will go far with your approach +1 I agree with swansont, it's not a waste.

Imagine LJ has never had a candy bar, and his family just gets by with a little petty theft; if you punish him by making him stand in the corner and after he served his sentence you give him the candy bar, he's far more likely to learn that stealing only achieved him the pain of being singled out (in his mind he probably thinks the rest of the class is laughing at him). What do you think he'll learn, if you also steal away his first ever chance eat a candy bar? Bearing in mind that his family has been teaching, theft is a necessary part of life; ergo he must get better at stealing... Every day is a lesson in life and every action has a consequence, we can never know now if it's going to be good or bad, that's why the past is best place learn about the present. It's far easier to damage society with punishment, if you don't understand the correct definition of punishment. And the odds are stacked against the majority of people getting the fact that most of them are wrong.

No, I'm not proposing we should do anything. I'm pointing out a fact that should not be ignored in the face of applying punishment or justice in an attempt to protect society at the same time. The criminal does the crime, serves the time and is released. As you correctly pointed out the justice system if working correctly should apply the right amount of punishment (incarceration, since this is the context we are discussing) that fits the crime. This we all agree on yes? My point which I'm not advocating we should do, other than consider the implications of releasing a violent offender back into society, especially if that criminal has not been rehabilitated enough to a level of acceptable confidence that they will not offend again. The only way we can guarantee society is protected from such a person is to lock them up for life or commit them to death. So to re-iterate a point I made earlier and it was thrown back in my face. Under certain circumstances imprisonment serves as punishment and protection for society.

No I am sorry if I did not make this clear. I think your youtube demonstration is a hoax or fake. We have discussed such demonstrations here before, if anyone can remember the reference. Hidden under the table or behind the background screen will be a generator of a changing magnetic field. The magnets you see are just showmanship.

Health care is NOT a joke !

You can't, agreed, we can never with a 100% certainty. But again sometimes [analogous to an hypothesis advancing to theory stage] the evidence is such [as per re-offending with the same crime after parole] that we must consider it as "highly likely" that a re-offence will occur...Not trying to teach Granny to suck eggs, but most scientific theory, remain as that, we are always open to further observational and experimental evidence, modifying or changing that theory. [1]which one is the greater danger? ANS: The obvious continued danger to society after throwing away a lifeline given to him.[previous parole] [2]How do you confine them for life without violating their rights? ANS: After throwing away their previous lifeline,[parole] coupled with the brutality and violence of the crime, not to mention "caught in the act" do they really have any rights left? Which incidently as I have mentioned, is why I am against the death penalty. That is reasonably final.😉

As studiot alludes, bulb type matters here, and more so what gasses are contained inside.

The internet is a wonderful resource. Unfortunately there are those souls who take delight in posting misinformation. Youtube hosts some really good videos of science and scientific explanations. Sadly it is also a target for hoaxes like this sounds to be. The 'bulb' is commonly a flourescent bulb, not an old fashioned filament or more modern LED type.

Whilst we are on the subject here is a question for you to think about. It is often thought that you cannot have a current without a voltage or a voltage without a current, but you can have either situation. Can you give an example of either or both cases, you should be familiar with at least one of them.
