hey guys welcome back i’m nate with the
king of random and today we’re going to
build a laminar flow nozzle laminar flow
refers to when water is traveling all in
exactly one direction with no turbulence
which means that when the exits a nozzle
it has a perfectly smooth stream so the
purpose of the video today is to learn
how to build our own laminar flow nozzle
without breaking the bank
here’s the supplies we’re gonna need for
this build we have the four inch
diameter plastic tubing you can use PVC
or ABS we have two of these test caps we
have a nozzle that attaches to a
standard garden hose some epoxy putty
coffee stirrer straws some screen door
mesh some starring pads and a can of
soda let’s start building this piece of
PVC I have is a little too long we’re
only going to need a piece about a foot
long so first I’m just going to cut this
in half so it’s a little more manageable
[Music]
now I’m going to cut off three rings
from the PVC tube each one about 1/4
inch wide
and now we measure for the main section
of to which should be between 11 and 12
inches long
[Music]
now that we’ve cut our pipe to length
the next step is to drill holes in each
of our test caps we want to use a drill
bit that’s the same size as the narrow
end of the threads that way it will have
a nice tight fit in the end cap for the
pipe fitting I have I’m using a
three-quarter inch drill bit later when
we drill the actual nozzle we’re going
to be using this 5/8 inch drill bit
using one of the quarter inch PVC rings
you’ve cut trace out the inside of the
circle on 2/3 of the scouring pads cut
along the line and you’ll have three
circles made from the scouring pads cut
through one of your quarter inch PVC
rings with the PVC rings we want to
figure out how much we need to cut off
in order to fit the entire ring inside
our PVC to
use your first cut ring as a guide to
mark on the other two where it’s cut cut
out three pieces of screen large enough
that you have a little bit of a border
around each of your PVC rings empty a
can of soda and rinse it out well using
a knife or a pair of scissors cut the
top and bottom off of your soda can be
careful because the jagged edges of the
can might be sharp you’ll want an unbent
piece of the kanwal about 3 inches
square sandwich a piece of aluminum
between two smooth boards and screw it
together tight making sure your screws
go through your sheet of metal this
piece of aluminum is going to be your
nozzle where the water comes out here’s
where we’re going to use that 5/8 inch
drill bit drill through the top board
and the layer of metal beneath it by
screwing into the metal sheet you should
prevent any movement you get a nice
clean cut once you finish drilling undo
the screws and remove your sheet of
aluminum trim the excess so you have
about a 1 inch border around the hole
you drilled drilling has probably left a
little bit of a burr on the aluminum so
we want to try and sand that off using a
very high grit sandpaper first I’m going
to sand it with 400 grit sandpaper and
then with some trip a lot steel wool
alright guys quick update we have now
cut prepped and prepared all of our
parts and it’s time to start assembling
our laminar flow nozzle first we want to
take our three sponges and press them
inside the tube leaving about an inch
and a half at the bottom next we want to
attach one of our screens to the ring
and press that into the tube place the
screen over the tube and then squeeze
the ring together so that the gap is
closed using a knife or scissors remove
the excess screen but leave a small
border around it being careful to apply
pressure to the whole ring at once lower
it and the screen down until it is
pressed up against the sponges now what
we’re going to do is fill the whole tube
with the coffee stirrer straws you’ll
want to make sure all of your straws are
pointing the same direction so the water
will flow smoothly if any of your straws
go in sideways make sure you straighten
it out we also want to make sure that
the entire opening is full of straws so
keep putting them in until there’s no
gaps left some people have tried
building these with regular drinking
straws and that might work pretty well
too but I think it works better using
these coffee straws so with the sponges
and the straws in place we have a device
that will mostly get the water traveling
in one smooth direction but we have a
little bit of space after the straws and
we want to make sure that the water
doesn’t start picking up any turbulence
we’re gonna put in two more layers of
the screens held in via the PVC rings
which should help prevent the water from
building up any turbulence before it
leaves the nozzle this first ring you
want to push almost all the way down to
the straw is leaving a gap of only about
a quarter of an inch the second ring you
only want to have about one inch below
the top of the tube now we’re going to
attach our flow nozzle to our end cap
we’ll attach a piece of electrical tape
to the flow nozzle but before we secure
it on flip it over and line it up to
make sure that the flow nozzle hole is
right in the center of the hole that’s
drilled into your end cap press the tape
onto the end cap to secure it in place
tape securely all the way around the
flow nozzle so there are no exposed
edges now that our flow nozzle is
attached to our cap we’re going to fit
that over our pipe
it’s probably a pretty tight fit but
with a little work you should be able to
fit the test cap into the end of the
pipe the last step before we test this
is to attach our hose nozzle to the
other end cap and attach that to the
pipe as well if you’re having a hard
time fitting the hose nozzle into the
hole you’ve drilled into the cap you can
expand it a little bit by using some
sandpaper once your nozzle is attached
to the end cap press the end cap down
into the pipe there you have it our
laminar flow nozzle is now ready for a
test fire before we make all of the
connections permanent okay so we’re
gonna hook our laminar flow device up
and I’ve removed the cap because we want
to see the water as it’s rising up you
can see just look how smooth this water
is you can see through it almost
perfectly because there’s no disturbance
to it you can see some air bubbles are
getting trapped underneath the screen
and even down on top of the straws so
I’m just gonna tip it try and get those
air bubbles together and come out
that is not laminar flow all right I’m
gonna turn the water off put the cap
back on and then see how this is flowing
out okay you can already see this is
working pretty well look at this little
stream it’s a it’s just this nice clear
jet you can easily see right through it
I’m gonna try turning up the pressure
just a little bit alright once again
that’s a higher pressure it’s still
going pretty well there is a little bit
of waviness right as it’s coming out of
the nozzle so one thing I’m just gonna
try I’m gonna turn off the water and I’m
gonna sand down the nozzle just a little
bit with some high grit sandpaper to
smooth it out just a tiny bit more
feeling all the way around that that’s
feeling pretty smooth by now there we go
that is a nice clean stream you can see
right through it it looks really good
let’s seal this thing up and make all of
the connections permanent alright as an
update we’ve now tested this and after a
little bit of additional sanding on the
nozzle to make it extra smooth it’s
working pretty well you probably saw
that a little bit of water was seeping
out the edges in the hose connector spot
so now what we want to do is seal up all
the connections so that it doesn’t leak
at all this two-part epoxy putty is
strong waterproof and holds up under
pressure just mix the two parts together
until you have a uniform color and then
you’ll have a minute or two to apply it
to whatever it needs to be glued alright
now that our putty is mixed we’re going
to take half of it and use it on the
outside and half of it on the inside of
our hose nozzle
[Music]
well the putty is carrying on the hose
nozzle we’re gonna use a little bit more
of it on the top of the cap to hold that
onto the device boozing out all over as
I squeeze this cap down onto the pipe
and you use a little bit of extra putty
to make sure that the gaps are really
well filled that’s one side attached now
let’s glue on the other one the putty
holding all of our nozzle pieces
connected is now dry and we’re going to
sand it just a little bit to clean up
the edges this is all sealed up and
ready to go but before we hook it up to
the hose again
you know here at the king of random we
like to decorate
[Music]
all right we’ve got this bad boy all
decorated let’s go hook it up to the
hose again here we go are working
laminar flow nozzle you can see look how
clean this whole line of arc is it
almost looks like a piece of glass but
of course if you touch it it splatters
everywhere a couple of tips if you’re
trying to troubleshoot your laminar flow
device because you’re not getting a nice
smooth flow out of it you’ll want to be
sure that you have at least two or three
of those sponges down at the bottom
because they really help slow the water
down so that the straws can do their job
of straightening all the water out
you’ll want to make sure that the straws
are all packed in tightly touching the
sides of the tube and if there are no
gaps and they aren’t moving around in
there the pieces of screen will really
help prevent any turbulence from
building up in the space between the
straws and the end of the nozzle and
lastly probably the most important thing
is that your nozzle has to be extremely
smooth it’s hard to spend too much time
on this if you can feel even the
slightest divot or burr or scratch in
the aluminum nozzle then that’s going to
affect the water flow all right one of
the main indicators that you have a good
laminar flow is that your water stays
together as a cohesive stream all the
way to the end look at how the water
coming out of this nozzle is still in a
tight stream even when it’s hitting the
ground when the water is truly moving
with a laminar flow it’s amazing how
clear it gets check this out
there you have it the laminar flow
nozzle as you saw it works pretty well
at low pressure at higher pressure the
stream does start to get a little bit
wonky and I know one of the reasons for
that is higher pressure especially out
of a garden hose is a little less
consistent I have plans for the future
to look into what I can do to make it so
that we have more consistent pressure so
that at higher pressures our stream of
water will travel farther let’s do a
quick recap of the build we took a piece
of PVC and added a hose intake valve the
water is slowed down by running through
some sponges and it’s then straightened
out by running through some coffee
stirring straws there are a couple
layers of screen mesh at the end to
prevent any turbulence from building up
in the dead space after the straws in
the tube it then exits through a
perfectly round super smooth hole all of
which gives us a perfectly smooth stream
of water with no turbulence so it almost
looks like a stream of glass coming out
of the nozzle there you have it you now
know how to build your very own laminar
flow nozzle without breaking the bank we
are hoping that we can revisit this in
the future to figure out how to add a
little more pressure and maybe some
fancy things like putting lights into
the stream of water thanks for joining
us for this project today and we’ll see
you in the next one
taki then there’s a giant fly now it’s a
dead fly hello the clouds did part and
the Sun did smile down upon them really
confusing they’re shot it’s just like a
drinking fountain with a lot of water
coming out hey guys just jumping in here
for a second to let you know that king
of random t-shirts are coming back by
your popular demand we’re bringing them
back the day after Thanksgiving that’s
November 24th so keep your eyes peeled
here on YouTube and watch my other
social media where we’ll be posting
links to where you can get your own
progression is uncomfortable and it’s ok
to feel awkward sometimes because it
means you’re pushing the boundaries on
your comfort bubble right now the king
of random brand is pushing the
boundaries of our bubble and expanding
as well and while we’re in this
transition phase I just want to thank
you for all you’re doing to support us
king of random and today we’re going to
build a laminar flow nozzle laminar flow

piece of the kanwal about 3 inches
square sandwich a piece of aluminum
between two smooth boards and screw it
together tight making sure your screws
go through your sheet of metal this
piece of aluminum is going to be your
