    Click clack I was taken aback. Wonderin’ ‘bout those switches of light, yeah.
    Let’s find out what the point is of all that clacking, shall we?

    Hey! Here are some fun links!

          Hah! I still have an ancient light switch that's totally silent! It has a sealed mercury tilt switch inside. Ooooo..... DEADLY!!! Not. But I can see why they stopped making these.
          Bet it was expensive in it's day.

              if you poke a light switch instead of smacking the wall as hard as you can you're living life wrong

                brains are funny things... i was rewatching this and during the "ooh a spark" portion I faintly smelled ozone each time... like happened with my old ionizer that gave off visible sparks if touched
                so my brain went "that bright thing makes this smell, so let's pretend we smell that"
                It stopped when you stopped playing with the plug.

                    God damnit when I was a kid I "always" tried to use switches applying force as slow as possible... If only I had known...

                      So to make sure that your switches continue to function normally, you need to use them normally.

                        There are clicks, and there are *CLICKS* . I find it annoying when the click is too loud. Call me sensitive. I've been called worse. :-)

                            Also when you break of an inductive load the voltage across will rise momentarily and the arch jump more easily.
                            The voltage across an inductor follows this equation v=L * di/dt which shows that the current through cant change instantaneously and therefore will compensate with higher voltage because of the large di/dt

                              wait... dont they switch polarity every 60hz?
                              "oscillations of alternating current (AC) in an electric power grid transmitted from a power .... As the 20th century continued, more power was produced at 60 Hz (North America)"... not 100-120. you were talking about 100-120volts...

                                On a 60Hz sine wave in one cycle it hits 0 twice before starting another cycle so his reversing 120 times per second is right

                                  So, I have some really crappy worn out rocker-style switches in my walls, are these a fire hazard if they aren't very clicky anymore!?

                                    They should make all switches wireless, that way they wouldn't have to run thick mains wires to every device from the switch. Hmmm...

                                                5:24 Wrong information... It's not "120 times a second" in the US we operate @ 60 Hz and that's 120 volts @ 60 Hz = 60 times a second. As the sine wave passes 0 60 times.

                                                  I have a clicky house with a clicky switch
                                                  Clicky is the sound of all that I hear
                                                  Clicky are the streets and all the trees are too
                                                  I have a girlfriend and she is so clicky
                                                  Clicky are the people here that walk around
                                                  Clicky like my Corvette, it's in and outside
                                                  Clicky are the words I say and what I think
                                                  Clicky are the feelings that live inside me

                                                    Speaking of power lines, do you know what the orange balls sometimes hanging off of power lines do? Are they put there so that the lines don't constructively interfere with themselves and shake themselves loose?

Back when I was 8 or so I used to put the switches in the half state because I enjoyed the crackling noise. The amount of life I needlessly ripped from the switches is unthinkable.
