Everything very well explained! Thanks!

We should spread more misinformation in the comments so Styro can upload more of these cool demonstrations!

Styropyro has the most sober crackhead energy I’ve ever seen. Like well spoken, up beat friendly dude. Let’s disco with death and play with lightning bolts lmao. Very smart very creative guy, love his uploads and personality. The dude is a YouTube gem 💎

How to prove something won't kill you: Normal People: math and common sense Styro:"If I do it and don't die it doesn't kill you'

I've been trying to figure out how old styropyro is, and I think this video confirms he's actually thousands of years old and is immortal.

Something I have learned as a rule of thumb for nearly all topics is that if someone tells you "it depends" rather than a simple straight answer, they are probably the real expert.

As an electrician and engineering student, this is one of the best videos regarding its subject. Especially for the short length. Very nice and informative. It is impressive that you are not an engineer or something like that.

PLEASE STOP THROWING APPLES OUT OF THE WINDOW THE DOCTORS ARE GETTING EXTREMELY SCARED

the fact that styropyro is still alive after all the stuff he's built and done.. he's got the most qualifications of anyone on the internet

I am an electrician. Hats off to you. I really did not know this in that much detail. You have a lot of cool instruments and a lot of knowledge. It must be fun to do this kind of thing and actually have the knowledge to keep yourself safe and know what you can get away with. I hope that you can keep exploring.

Electricity in a nutshell is basically, "Yes, but no. It's complicated."

If that tesla coil wont kill you, your electric bill will :D

I also can't stand it when people try backing up their false claim with their qualifications, or when they're so confident and condescending, and wrong at the same time. Which is why I absolutely love this video. You proved that they are unequivocally wrong through the fact that you're not dead.

One of the few individuals who takes in feedback, responds in kind and manages to educate people. Cheers to you, mate.

As an electronic tech of nearly 20 years working on everything from xray supplies to consumer devices tube and solid state I absolutely agree. Glad someone else understands its not an exact science to getting zapped, depends on many factors even down to your body hydration level how severe of a shock you will get. Most of the equipment I work on uses 450vdc + as its main rail voltage with over 10A available continuous. You work one handed, I was spared once as a younger/more dumb/careless individual and got away with burns and getting knocked the fuck out. I was working on a large linear tube transmitter and didn't discharge the rail. Be careful out there guys especially with those damn microwave transformers, like the man said they are no joke and everybody is playing with them and sometimes when you play stupid games.....you get stupid prizes.

7:54 What is that editors note?! Lmao

I'm a EE but it's been so long since I've done anything remotely related to my education that I probably couldn't design my way out of a paper bag. However, this video brought back a lot of fond memories and reminded me why I wanted to become a EE in the first place. I wish resources like this existed 30+ years ago when I was in school. Great video!

Very well explained! I work in the electrical power industry, and like most, I’ve always been told “it’s not the volts it’s the amps.” My understanding was always that, yes, it is the physical flow of current through your body that causes the damage, but in order for significant current to flow, it depends on many factors such as voltage, frequency, impedance, dielectric breakdown, etc., just as you explained. Well done!

A great video. As an "expert" in the area I can add a few more refinements: the biggest risk for cardiac arrest is when the current changes polarity just at the right time in the heart's re-polarizing process, which messes up the timing and causes fibrillation. This "critical" period might be in the order of 5ms (I don't know this for sure, but it is short). Thus you can have for example 50Hz current for a short time, and nothing (much) happens just by chance as the zero crossing didn't happen at the right time or direction. The longer the current exists, the higher the probability of getting the zero crossing and polarity at the right (or should I say wrong?) timing. Frequencies in the zone of 20-500Hz have highest risk because frequencies are low enough for the cells to respond while still having a high enough rate of change at the zero crossing to mess up the heart's re-polarization. Unfortunately it just happens that our ac mains of 50Hz or 60Hz is smack bang in the middle of the dangerous region. But even medium voltage dc can be dangerous if you were unlucky enough to touch it just at the right time when your heart was re-polarizing, and you got the polarity right. With respect to skin impedance: this does a great job of protecting us, but there are situations where the skin is bypassed, such as liquids, electrodes, large surface areas. For example, in a pool it has been demonstrated that a 6Vac circuit was enough to kill a child because it stopped them being able to swim. When the skin is bypassed, the body presents about 1kΩ impedance, so in that instance it would have been in the order of 6mA, which is enough to cause involuntary muscle action, although below the threshold for cardiac issues. Involuntary muscle action can also be dangerous e.g. if you are on top of a ladder, driving a car, performing surgery on a patient, which is why standards for electrical safety don't go anywhere near the cardiac threshold which is about 40mA. If fact, standards for electrical equipment normally have limits in the order of 0.1mA under normal condition. Literature often suggests that the threshold of sensation is about 2mA, but this is not correct. For sensation, the correct parameter is current density (e.g. mA/cm²) as opposed to absolute current. If you spread 1mA over 1cm² you probably would not feel it. But with higher voltages, an arc can form just prior to contact, which concentrates the current into less than 1mm². Under that condition, 1mA is painful, an even currents as low as 0.05mA can be felt. So in that case, the open circuit voltage also affects the outcome, since it determines if an arc can occur allowing the current to be concentrated.

Finally! This clears up so much about the dangers of electricity for me. I work with electricity A LOT, but it has always sort of terrified me because I haven’t been able to grok what is and what isn’t dangerous. I’ve seen those unhelpful graphs and even watched presentations on electrical safety that were almost no help at all. This video has finally cleared up so much for me that I will no longer be terrified to complete the circuit on my 12v batteries, even though a misplaced wire can result in unwanted spot welds 😂
