Nitrogen Propelled Rocket Launcher (N.P.R.L.)


where is it hey what’s up guys today I’m
hanging out with Sean ders
liquid-nitrogen no big deal
see a lot of you know that I replenish
my recent supply of liquid nitrogen and
this stuff has a shelf life so while
we’ve got it we’re putting it to good
use and we’re revisiting the nitrogen
rocket project but with a twist
we got an idea rocket launcher what do
you think can we make it work we’ve
never done this before we really have no
idea how it’s gonna get any amazing is
what its gonna be what’s the danger
level of all this stuff I feel like
there’s a lot of peer pressure in this
video that’s gonna go down if it touches
your skin just freak out like it’s a
spider and you’ll be okay yeah right in
the middle of the road that’s awesome
that’s not conspicuous at all pick up
that big tank and that stuff is
extremely expensive so don’t spill any
we just have two problems problem number
one I’m I’m scared of liquid nitrogen
problem number two I don’t have big
muscles to lift this thing well give me
your best shot okay here we go
nobody’s judging whoa dude
there’s money looks you see a like
bubbling and spitting right on the top
that’s insane alright is this your first
time with liquid nitrogen
oh no I do this like every day all day
alright so we got our water bottle you
can see it’s about half-full of just
regular tap water room temperature a
little bit of liquid nitrogen we don’t
have a whole lot of time to play with
here so let’s get you going on this
before that water freezes up oh shoot
alright just grab that bottle and flip
it right upside down right down yeah
good rocket launch oh this is so doable
now you see it easy yeah next trip Home
Depot we’re gonna go pick up some
materials and see we can makeshift the
rocket launcher I mean that was kind of
cool but imagine wrong like
there’s our rocket bodies right there
these 500 millimeters have really
durable plastic so they work great gotta
get green it’s like army rocket launcher
green I’m diggin that army missiles
let’s get it all right so we just got
back from Home Depot we’ve got all our
materials and all we’re using it for
this rocket launcher is a 4-inch piece
of PVC pipe we’ve also got these four
inch couplings
these are ABS and they’re black so we
don’t need to paint them they look cool
as is these are going to go on either
end to the rocket launcher and then
Sean’s idea was to use this for a handle
which is actually pretty cool this is a
1/2 inch connector t and we’re going to
just basically slice that off
bend the plastic and melt into the
bottoms that we’ve got built in handled
now it’s going to take a little bit of
time for this to warm up because we
don’t want it to catch on fire burns but
this could take a while
this could take a couple of minutes but
the keys just be gentle and keep it
moving it’s worth it a turtle wins the
race
so can look how rubbery that is yeah
okay so you just kind of hold that down
or why don’t you go find a cloth or
something in we just want to hold this
thing against that pipe and get the
sides as flat as possible the more
surface area we can make contact with
the better this thing’s gonna stick you
see this is rocket launcher sign alright
there we go it’s smooth cool I’m heading
we’re in business
[Music]
all right we got our little handle
formed here it fits pretty nicely we
just got to figure out what feels right
for Gallants I’m holding on to the back
here by the coupling because that’s
where the Rockets going to enter right
about there feels pretty awesome so go
ahead and Mark that oh now it’s time to
glue it up now we’re gonna need some ABS
to a PVC cement like this stuff and
check this out the green you’ll expect
totally really do it kinda looks like
slime you gotta work it one bit while
that’s sitting let’s go work on making a
rockets next now when it goes to making
your rocket bodies that’s the kind of
bottle you want to get something that’s
a 500 milliliter soda bottle because
it’s pressure ated and that’ll be able
to contain the liquid nitrogen as it’s
expanding rapidly the thing about these
soda bottles is they’re really flat on
the bottom and so they’re not
aerodynamically stable when they fly up
into the air they tumble with all over
the place
so we need to do is cope with some kind
of a nose cone cut this off take the
bottom part of this bubble the top part
of this bottle the bottom part of here
and now we’ve got aerodynamic ammunition
I think that I’ll deal funny looking is
that which n do it in front it’s a
teamwork model now the reason we got the
four inch PVC tube is because these
bottles when you put them inside you see
lead is a little bit of a gap around the
edges and that’s where we’re going to
build our fins we worked out some kind
of little fin template here that almost
matches the Bulge there it doesn’t have
to be perfect he’s hot glue fill in the
gaps and that should mesh together
pretty well
[Music]
we’re also going to need to add a couple
loves you here to balance the top end
when it sits in the rocket as well now
when you okay the rocket launchers then
build class
[Music]
funny story this is the actual
spray-paint I used when I build my
rocket rifle four years ago which was
one of my first videos and sentimental
what you can want to do here is just
with gentle hands go like that gentle
hands though you want to keep those
hands gentle you want to do I’m just
gonna set this down for a few minutes
and let it dry I just throw you so I
think I roughed in all the cardboard oh
where was I when you made this and I
might have to trim these fins up a
little bit I think that’s gonna be our
rocket right there I’m just gonna give
it a hit of black spray-paint to make a
look but definitely do that yes 100% and
maybe a little bit of green camouflage
bolts they won’t see it coming our rock
gets pretty much done painted black with
some spray paint and the cool thing
about using a bottle top is that you can
still unscrew it there’s a cavity in
here or you can add some weight I’m just
going to put a little bit of sand in
there and that’s going to shift the
center of gravity forward and make this
thing a little more aerodynamic so check
it out guys our project is done we’ve
got some pretty cool-looking equipment
we’re ready to launch rockets liquid
nitrogen missiles to be exact so if you
want to see how that turned out go check
out the shonduras channel we’re gonna be
there getting ready to rock it rock it
wait you say rocket
okay guys we just got back from filming
in the garden I cannot wait to show you
the footage that we got what you’re
gonna see on this guy’s video we
exploded in the missile it up and away
in the ground I made a hole like this
big all that yeah just watch it but
it’s good now if you’re wondering who
shonduras is I met him at CVX live he’s
really cool guy nobody FS so these guys
in about five seconds what you do and
your five swing it’s fun it’s fun so if
you’re like daily blogs for watching
like random adventures he’s always
getting it bosses skateboarding
snowboarding shredding falling getting
hurt awesomeness alright so go check
them out and thanks for joining us again
we’re gonna see you guys the next video
with some other random project talk to
that
