hi trying to focus
yeah one million subscribers
well this calls for two things first i
like to make a celebration candle which
i'll make out of a jacob's ladder
and second i'm gonna give away four of
these logs about mini
3d printers to you my viewers and
patrons at the end of the video
thank you for helping me get there now
let's make a ladder
according to historians jacob used this
special ladder to ascend to heavens
well naturally of course if you are too
unfortunate to touch this ladder you'll
die
because it's made of very high power
high voltage low frequency across two
metal rods
but unlike the legend it doesn't
guarantee you will go to heaven
unless you have led an honest life have
been good to your neighbors
fine i don't know why they call it a
jacob's ladder and i don't care we need
high voltage and i can create it with my
microwave oven transformer it creates
over 2000 volts
now we need to shape two wires and
connect them to the transformer
hey i just came back from future to warn
you one last time
you are banned to do this high voltage
experiment at home
it is more dangerous than having an
agitated cobra around your neck
at least the venom takes a while to kill
you but this doesn't
in a jacob's ladder we have two wires
like this connected to high voltage
the arc is created from the shortest gap
and rises all the way up the reason is
that the arc is hot so the hot air
pushes the arc up
i connected my wires to the transformer
so we can see the arc
oh i think the gap between the wires is
a little bit too wide for the two
kilovolt to jump across
i almost killed myself but i was saved
with sheer luck
see my right hand touch the wire first
which shocked me back to my senses
if both my hands touch the wires at the
same time now you would be watching a
few hours of my corpse cooking to
perfection
i'm pretty sure that doesn't meet
youtube guidelines either
maybe i could have posted a live leak so
never get too comfortable around high
voltage and always wear protective gear
see even though only one hand was
touching the wire and fortunately i
wasn't touching earth or any other
conductive surfaces it still zapped me
always remember any conductor like your
body has parasitic capacitances to the
environment
so if the voltage is high enough there
will be high enough currents to zap you
let me show you see this probe is not
connected anywhere
but when i bring it close to this wire
it'll arc
you hear it maybe if i make the room
dark you can't even see the arcs
you see them the probe is still not
connected anywhere
if it was the arcs would be huge
for around two kilovolts i need around
one millimeter for the arctic
anyways for around two kilovolts i need
around one millimeter of air gap for the
arc to jump
let's try it
my puny wires melted i need thicker
wires like this so they won't melt
let's give it a try come on
the breaker popped damn it i just want
to celebrate
apparently the one millimeter air gap is
too short for the arc to rise
i need to widen the gap but then that
means that i have to have
much higher voltage which i could make
using a simple circuit like this to
increase the output voltage peak to
double
the problem is that the capacitorized
scavenge from my microwave oven is
broken
and all i have are these hundred
picofarad high voltage capacitors which
limit the output power a lot
let me show you here i have a single
capacitor series with my power supply
and you can see that
around one millimeter the arcs
start jumping
now all i did is that i added the diode
i talked about earlier
and we can see that the arcs
can jump from a much further distance
this is too weak for jacob's ladder
though because as soon as i open the gap
it stops going
we need more power to be able to stretch
the arcs see
[Music]
for a wider arc we need more power to
create and maintain
a longer ionized air channel
so i guess i can keep the gap wide and
then stretch an arc across
it manually like this
so emmanuel jacobs letter
i think it still needs more pizzazz
what if i put a capacitor between the
rods so that when the arcs
reach them the capacitor blows up for
some firework effects
here's the capacitor ready
[Music]
the capacitor legs melted but the
capacitor didn't blow up
is anything gonna work today so much
power melted the legs but the capacitor
is not even bulged
let me check something
that's why it seems like the high
voltage that shorted the capacitor
internally
before it even had a chance to heat up
and blow up
worst celebration candle ever
hey what if i put some matches between
them so at least they
set on fire i'm holding a match there
let's give it a try
[Music]
fire fire creates plasma
let me introduce you to fire
[Music]
we don't need high voltage after all
[Music]
breaker and what if i add some sparklers
to it
it's getting there
[Music]
oh my god
[Music]
let's make it fancier i designed a stand
for my fancy jacob's ladder and i'll
print it
so i'll be giving away this lulzbot mini
3d printer
it's a pretty solid printer i've had it
for over a year now
and printed a few things with it
very useful tool to have
it is a two piece part which i'll glue
together like this
and i'll drill the burrs out of the
holes
and so we have a shrine
i leave a link to the 3d model in my
website in case you need it for
spiritual reasons of course you didn't
think i was going to use these tiny
sparklers eh
say hello to my 28 inch sparkler
put them in let's add a bunch of more
tiny sparklers to it
let's start the mayhem
the hell the hell
why bad things happen to good people
go
[Music]
thanks to my flimsy wire connections to
the transformer that fell off quickly
i only sustained some third degree burns
my stupid long sparklers made my
structure top heavy which of all people
fell right on top of me
i leave a bunch of safety tips on my
website but such experiments are not
worth dying for
so don't do it let's just celebrate like
normal people with oversized sparklers
[Music]
yay
[Music]
[Laughter]
[Music]
foreign
[Applause]
[Music]
come on
[Music]
oh
[Music]
hey i survived a million subscribers and
hopefully i will survive another million
too
and to show my appreciation to everyone
who made this happen
i thought giving away a few 3d printers
is in order
glossbot makes some top of the line
printers i've had this largebot mini for
a while now and i'm pretty happy with it
and i thought you deserve the same
so i give two of these to my patrons at
patreon.com who are automatically in the
draw
and the other two go to the viewers so
like last time if you have a need for a
3d printer leave a comment so i know you
need it something like
loves my butt loves butt i don't know be
creative bring smile to my
face and thank you again
