if we dumped a puddle of liquid nitrogen
straight into the palm of our hand how
long do you think it would take for the
skin to cool down enough to where the
nitrogen could latch on and bite it now
in previous videos I’ve showed you that
you can take liquid nitrogen and splash
it in your face or roll it off your
hands with little to no effect and
that’s because the latent Frost effect
basically vaporizes the nitrogen into a
gas which shields you from the intense
cold of this liquid but what do you
think would happen if we left the
nitrogen in one place for a little bit
too long for example what if we poured
this into our hands and just let it sit
now if we’re to take a little bit of
this liquid and just pour it in the palm
of our hand but we keep our hand moving
fast enough you can see the liquid
doesn’t actually do any damage
it just skittles around kind of like
playing a game of air hockey until the
nitrogen completely evaporates but what
would happen if we stopped moving our
hand and let the liquid nitrogen settle
down and stay in one place for a little
bit longer okay so this is where I start
getting a little bit more nervous I
don’t want to stop moving my hand
because I know what’s going to happen
but watch this if I do stop for a second
watch right there you can see it
actually instantly frostbites the skin
let’s do that again with a little bit
more liquid that’s just gonna whoa you
can see immediately it starts frostbite
of me and as it warms up it disappears
as quickly as it can now to me this
feels like a little bit of a bee sting
almost like I got stung and the pain
lingers for about 10 to 20 seconds you
can see the skin is turning a little bit
red there it’s not to the point of where
will be a first-degree burn just yet but
it would be if we left it exposed a
little bit longer let’s try a smaller
bead here let that settle down oh oh
okay I chickened out
I don’t really want to keep this going
much longer I’m gonna try one little
bead and see if I can make it all the
way through this may not be the smartest
idea but I’m doing this for you go
there’s a nice little bead we’ll let it
settle down in
oh man that can actually hurt so you can
see it’s turned my skin completely white
as it warms back up though it starts to
fade you can see this is taking about 10
to 15 seconds now I do feel a little bit
of pain there it is a lingering
sensation it feels like after you got
stung by a bee and you can see the
coloration in the hand is a little bit
more red but even at this point I
wouldn’t consider that a first-degree
burn it might be an extreme case of
frostnip but I wouldn’t expect that to
blister up you can see it only takes a
fraction of a second for nitrogen to
actually grab onto your skin and start
burning it
and the reason I say burn is because
frostbite is actually very similar to
first second and third degree burns
depending on how long you’re exposed I
wanted to show you this reaction because
I’ve done a lot of experiments with
liquid nitrogen and I didn’t want you to
get the impression that it was super
safe stuff to play with
you can see that it will burn you and it
will burn you very quickly and it does
hurt and leaves a mark it might be
wondering what this feels like and right
now I have lingering sensations all over
my hands as if I was stung by bees
multiple times there is a lingering pain
in that part of my hand almost like
somebody’s taking a nail and pressing it
down in my skin I get an itchy tingling
sensation that makes me want to scratch
it so if you do happen to get
frostbitten this is the way that you
want to treat it get yourself a bowl of
lukewarm water you do not want it to be
hot and you don’t want it to be cold
just lukewarm or room temperature and
just soak the area for a couple of
minutes until it starts to feel better
then take a warm dry cloth and press it
to the affected area and just hold it
until it starts to warm back up now
depending on the severity you might want
to go seek medical attention and see
what your doctor has to say so how long
does it take for liquid nitrogen to
freeze your skin well according to my
experiments it only takes a fraction of
a second if you leave your skin exposed
any longer than that it’s going to start
freezing the muscles freezing the
tendons you could actually get to the
point where you freeze your entire hand
solid and that would not be a very good
day that’s all I got for this experiment
I’ll see you in the next video talk to
you then
