whoa that was cool sup guys welcome back to the lab I’m
sup guys welcome back to the lab I’m
sup guys welcome back to the lab I’m grant Thompson the king of random and
grant Thompson the king of random and
grant Thompson the king of random and i’m derek from the youtube channel
i’m derek from the youtube channel
i’m derek from the youtube channel veritasium and today we are playing with
veritasium and today we are playing with
veritasium and today we are playing with fire and ice i just got back from the
fire and ice i just got back from the
fire and ice i just got back from the gas station where I picked up this bag
gas station where I picked up this bag
gas station where I picked up this bag of ice but this is no ordinary bag of
of ice but this is no ordinary bag of
of ice but this is no ordinary bag of ice you see when we pour this ice into a
ice you see when we pour this ice into a
ice you see when we pour this ice into a bowl and light it off with a torch you
bowl and light it off with a torch you
bowl and light it off with a torch you can see that the ice burn why is that so
can see that the ice burn why is that so
can see that the ice burn why is that so we’re gonna come clean guys this bowl
we’re gonna come clean guys this bowl
we’re gonna come clean guys this bowl wasn’t completely empty when we dumped
wasn’t completely empty when we dumped
wasn’t completely empty when we dumped in the ice I first sprinkled on a fine
in the ice I first sprinkled on a fine
in the ice I first sprinkled on a fine layer of a chemical called calcium
layer of a chemical called calcium
layer of a chemical called calcium carbide DAC 2 now this calcium carbide I
carbide DAC 2 now this calcium carbide I
carbide DAC 2 now this calcium carbide I just went to in a chemical supply store
just went to in a chemical supply store
just went to in a chemical supply store and picked up for about 56 dollars but
and picked up for about 56 dollars but
and picked up for about 56 dollars but the stuffs actually been used for
the stuffs actually been used for
the stuffs actually been used for centuries originally it was used in
centuries originally it was used in
centuries originally it was used in miners lamps they would put it in add a
miners lamps they would put it in add a
miners lamps they would put it in add a little bit of water and it would pump
little bit of water and it would pump
little bit of water and it would pump out acetylene gas that they could light
out acetylene gas that they could light
out acetylene gas that they could light and that’s how they would light their
and that’s how they would light their
and that’s how they would light their way in the mines funny enough calcium
way in the mines funny enough calcium
way in the mines funny enough calcium carbide its main purpose today is to
carbide its main purpose today is to
carbide its main purpose today is to still produce acetylene gas and when you
still produce acetylene gas and when you
still produce acetylene gas and when you mix acetylene with oxygen it produces
mix acetylene with oxygen it produces
mix acetylene with oxygen it produces one of the hottest flames burning around
one of the hottest flames burning around
one of the hottest flames burning around 3,500 degrees Celsius which is
3,500 degrees Celsius which is
3,500 degrees Celsius which is ridiculous that is really hardcore if we
ridiculous that is really hardcore if we
ridiculous that is really hardcore if we pour some of the actual calcium carbide
pour some of the actual calcium carbide
pour some of the actual calcium carbide out here you can see what it looks like
out here you can see what it looks like
out here you can see what it looks like they almost look like little grayish
they almost look like little grayish
they almost look like little grayish black granules of rock not super
black granules of rock not super
black granules of rock not super exciting until they make contact with

water the instant that stuff touches
water the instant that stuff touches water it starts releasing this misty
water it starts releasing this misty
water it starts releasing this misty white vapor which is extremely flammable
white vapor which is extremely flammable
white vapor which is extremely flammable and as we’ve just experienced as soon as
and as we’ve just experienced as soon as
and as we’ve just experienced as soon as it’s lit it’s a very very hot flame and
it’s lit it’s a very very hot flame and
it’s lit it’s a very very hot flame and we could feel this from quite a distance
we could feel this from quite a distance
we could feel this from quite a distance yeah yeah we just lit ice on fire that’s
yeah yeah we just lit ice on fire that’s
yeah yeah we just lit ice on fire that’s really cool let’s talk about that for a
really cool let’s talk about that for a
really cool let’s talk about that for a second I actually have a little molecule
second I actually have a little molecule
second I actually have a little molecule kit let me should I bring it over here
kit let me should I bring it over here
kit let me should I bring it over here so the calcium carbide has two major
so the calcium carbide has two major
so the calcium carbide has two major components obviously your calcium and
components obviously your calcium and
components obviously your calcium and your c2 and their triple bonded these
your c2 and their triple bonded these
your c2 and their triple bonded these are carbons that are triple bonded you
are carbons that are triple bonded you
are carbons that are triple bonded you add in some water what ends up happening
add in some water what ends up happening
add in some water what ends up happening is they break apart the calcium off of
is they break apart the calcium off of
is they break apart the calcium off of there and you form calcium hydroxide
there and you form calcium hydroxide
there and you form calcium hydroxide which is ca o h2 like that and then the
which is ca o h2 like that and then the
which is ca o h2 like that and then the hydrogen’s end up going on there and
hydrogen’s end up going on there and
hydrogen’s end up going on there and that creates your acetylene gas also
that creates your acetylene gas also
that creates your acetylene gas also known as a sign and this is a very
known as a sign and this is a very
known as a sign and this is a very flammable stuff that reacts with oxygen
flammable stuff that reacts with oxygen
flammable stuff that reacts with oxygen and creates a very very hot flame that
and creates a very very hot flame that
and creates a very very hot flame that is an amazing reaction what I think is
is an amazing reaction what I think is
is an amazing reaction what I think is so cool about it right is that when you
so cool about it right is that when you
so cool about it right is that when you do it on I you start it with just a
do it on I you start it with just a
do it on I you start it with just a little bit of water so you just get this
little bit of water so you just get this
little bit of water so you just get this reaction starting get a little bit of
reaction starting get a little bit of
reaction starting get a little bit of acetylene but then of course once the
acetylene but then of course once the
acetylene but then of course once the fire kicks in now more ice create more
fire kicks in now more ice create more
fire kicks in now more ice create more water that for
water that for
water that for the reaction producing more acetylene
the reaction producing more acetylene
the reaction producing more acetylene and it’s like a self feeding cycle
and it’s like a self feeding cycle
and it’s like a self feeding cycle exactly what I find is really
exactly what I find is really
exactly what I find is really interesting and I’m not sure what
interesting and I’m not sure what
interesting and I’m not sure what exactly is going on here but look all
exactly is going on here but look all
exactly is going on here but look all the soot look at all this black residue
the soot look at all this black residue
the soot look at all this black residue right here and we’ve got little chunks
right here and we’ve got little chunks
right here and we’ve got little chunks floating around in the air and it what’s
floating around in the air and it what’s
floating around in the air and it what’s really interesting is we just have this
really interesting is we just have this
really interesting is we just have this calcium carbide and ice like nothing
calcium carbide and ice like nothing
calcium carbide and ice like nothing else went into it and now we’re left
else went into it and now we’re left
else went into it and now we’re left with bubbles and what an interesting
with bubbles and what an interesting
with bubbles and what an interesting smell did you smell the gas coming off
smell did you smell the gas coming off
smell did you smell the gas coming off as well yeah I did yeah it’s not quite
as well yeah I did yeah it’s not quite
as well yeah I did yeah it’s not quite the smell of rotten eggs it smells a
the smell of rotten eggs it smells a
the smell of rotten eggs it smells a little bit different but I would put it
little bit different but I would put it
little bit different but I would put it in the same family the sound category
in the same family the sound category
in the same family the sound category it’s a little bit like like gunpowder
it’s a little bit like like gunpowder
it’s a little bit like like gunpowder yes what if it’s not like them yeah
yes what if it’s not like them yeah
yes what if it’s not like them yeah almost like a burned rotten egg smell
almost like a burned rotten egg smell
almost like a burned rotten egg smell yeah for sure but very very flammable
yeah for sure but very very flammable
yeah for sure but very very flammable who knows what that would do to your
who knows what that would do to your
who knows what that would do to your body something super I’m sure was basic
body something super I’m sure was basic
body something super I’m sure was basic right so it would dissolve a lot of
right so it would dissolve a lot of
right so it would dissolve a lot of things it dissolved your flesh yes
things it dissolved your flesh yes
things it dissolved your flesh yes calcium carbide is pretty cool but one
calcium carbide is pretty cool but one
calcium carbide is pretty cool but one of the things that’s made me wonder is
of the things that’s made me wonder is
of the things that’s made me wonder is where does it come from how is it made
where does it come from how is it made
where does it come from how is it made and as I did a little bit of research
and as I did a little bit of research
and as I did a little bit of research what I found is in an industrial process
what I found is in an industrial process
what I found is in an industrial process they actually use an arc furnace with
they actually use an arc furnace with
they actually use an arc furnace with carbon rods and take coke and lime and
carbon rods and take coke and lime and
carbon rods and take coke and lime and burn it together at very high
burn it together at very high
burn it together at very high temperatures around 2,200 degrees
temperatures around 2,200 degrees
temperatures around 2,200 degrees Celsius so you could probably do that
Celsius so you could probably do that
Celsius so you could probably do that with your backyard foundry right well
with your backyard foundry right well
with your backyard foundry right well maybe not the backyard foundry but I do
maybe not the backyard foundry but I do
maybe not the backyard foundry but I do have a mini arc furnace ah which is
have a mini arc furnace ah which is
have a mini arc furnace ah which is basically the same thing on a smaller
basically the same thing on a smaller
basically the same thing on a smaller scale so I wonder could we produce
scale so I wonder could we produce
scale so I wonder could we produce calcium carbide that might be an
calcium carbide that might be an
calcium carbide that might be an experiment for another day so there you
experiment for another day so there you
experiment for another day so there you have a guys now you know how to use a
have a guys now you know how to use a
have a guys now you know how to use a little bit of calcium carbide to make
little bit of calcium carbide to make
little bit of calcium carbide to make fire on I this is a very cool experiment
fire on I this is a very cool experiment
fire on I this is a very cool experiment very very messy very very dangerous but
