I just made a laser-guided blowgun for
under $3 but don’t let its simplicity
fool you it’s powerful enough to break
glass even blast darts into concrete in
this project we’re making a custom laser
sighted blowgun that not only looks cool
but adds another dimension to the fun
you can have in the backyard let’s start
this project with a roll of scotch tape
a stack of sticky notes and a paper
party hat I’m using the small 2×2
squares and if we wrap one carefully
around the tip of the hat the cone shape
acts as a forming guide for making a
pointy paper dart we’ll need a little
bit of tape to reinforce the tip and
hold it all together so when it slides
off it’ll still keep its conical shape
now watch what happens if we push the
tip into a half-inch PVC tube and give
it a little twist you can see the
pressure leaves a little mark right
where it starts getting too big for the
tube let’s carefully trim along the
inside edge of the marking and just like
that we’ve made a mini paper dart that
will fit perfectly inside the blowgun
barrel but it’s not quite ready to use
yet we still need to add some weight to
the tip so they’ll fly straight I found
one of the quickest and easiest ways to
do that is to squirt a little hot glue
inside the cones until they’re about a
third of the way full if you don’t have
hot glue try pulling off a little piece
of poster putty instead and shove it
down into the tip with something like a
screwdriver that’ll work just as good
all right we’ve got some paper darts all
we need now is a blowgun so let’s work
on making that next I went to the
hardware store and pick up a two-foot
length of half-inch PVC pipe and a
reducing adapter this female adapter is
three quarters of an inch on one side
and reduces to a half inch slip
connector on the other now if we simply
push the adapter onto the tube and give
it a little tap we’ve just created a
super simple blowgun that can be used
right away you can see the weighted
darts fly amazingly straight and we’ll
take out paper cups with an impressive
amount of power they’re just strong
enough to do a little damage but it’s
still safe enough to shoot around the
house not that you should but you could
alright let’s take the system to a whole
new level with a roll of duct tape and
some wire nails I got this roll of
camouflage tape from the hardware store
and we’ll need to start by putting a
long strip on the table with the sticky
side facing up now watch this if we
carefully set the pipe lengthwise in the
center of the tape then gently rock it
from side to side the tape will start to
wrap itself around the two
doing the same thing with a second piece
of tape will cover any gaps and just
like that our plugins got a custom camel
wrap now just add some electrical tape
around the tip of the barrel and around
the mouthpiece to cover the rough edges
and make it look a little nicer at this
point you can see our blowgun is
starting to look pretty serious so let’s
get busy making some rounds of
ammunition they’re a little more serious
as well I’m using number 16 and number
18 wire nails because they’re relatively
lightweight and have a nice flat head on
the top you can see when a nail gets
pushed through an empty paper cone it
instantly transforms into a high speed
nail dart it’ll work find us like this
but to make it a little more durable try
adding a dab of hot glue on the inside
of the cone then pulling down on the
nail until the head catches firmly at
the bottom they’ll need about two
minutes for the glue to cool and Harden
so while we’re waiting why don’t we try
making something a little different a
stack of colored sticky notes will make
different colored darts and just for fun
I sniff the tips off these purple ones
and drove small screws deep into the
glue I call these ones my glass breakers
and you’ll see how they got that name in
just a minute now if you want to
experiment with different types of darts
you can really use any length of nail
you want smaller darts will be easier to
shoot and fly faster while heavier darts
will penetrate deeper and do more damage
now that we’ve got some good ammunition
we’re gonna need a way to store it
I found a six-foot length of half inch
foam pipe insulation for a little over a
dollar and tried cutting little donut
shapes off the end about 3/4 of an inch
thick I used some electrical tape to
reinforce the outside of the disc then
just for looks used a black marker to
color the foam a little bit darker the
next step is to make another foam disc
the exact same way and then slide both
of them onto the barrel of the blowgun
at this point we’re ready to modify the
quiver so it’ll carry eight rounds of
ammunition
I found a Phillips head screwdriver and
carefully heated it over a flame for
about 20 seconds that gives it just hot
enough to burn little holes into the
foam on contact just make sure you’re
only burning holes in the top discs
because we’re gonna want the bottom one
left intact you can see the eight holes
we made space the darts evenly and guide
the nails as they push down into the
padding below these makeshift Quivers
keep all the darts securely in place
while protecting the tips of the darts
at the same time alright our customized
blowgun is looking pretty impressive and
we could stop here let’s go one step
further and give it a laser I picked up
a red laser pointer from the dollar
store and hot glue
eight and a half inches back from the
tip of the barrel then reinforced it
with a couple of zip ties for durability
the thing I like best about these $1
lasers are how one button operates an
LED flashlight while the other activates
a laser sight making this system
operable in the dark now I got a
slightly better laser from the pet
section of the grocery store and turned
it into a custom laser scope that
complements the gun really well with
this setup the position of the laser can
be fine-tuned with amazing precision
which you can see results in supremely
accurate shots alright now that we’ve
got a custom laser guided blowgun let’s
have some fun
I took mine outside and found that the
darts easily penetrated in a wooden post
without even trying
they’ll also stick into tree trunks or
completely abused the side of a wooden
deck like the one on my kids Playhouse I
was able to hit some targets from over a
hundred feet away and if I miss the
darts just sailed right into the
concrete wall behind it which actually
blows my mind completely I still don’t
really know how these stick in there
cinderblock but they do for one last
experiment I tried loading one of the
glass breaker rounds and fired it a
glass full of water needless to say they
do live up to their name now you’ve
probably realized that if you use
different rolls of tape you can
customize your blowgun any way you want
and if you want a safer kind of ammo try
using colored mini marshmallows they’re
the perfect fit for half-inch PVC and
can be shot safely but still with
incredible accuracy well now you know
how to make an incredible laser-guided
blowgun that will rattle off nail darts
with power and precision the best part
is if you make these in bulk they can
cost as little as 250 each and that’s
including the $1 laser well that’s it
for now if you liked this project
perhaps you’ll like some of my others
check them out at the king of random
calm hey guys I had a lot of fun
developing this project and I’m really
excited because this one is cheap and
easy enough that anyone can do it I want
to give three of the blow guns from this
video to three of you and I’m happy to
pay out of my pocket to ship it to you
wherever you are in the world what I’m
asking for in return are just two things
number one follow me on Google+ Facebook
Twitter and any of the other social
media sites and number two share one of
my videos or post a project that you’ve
tried using the hash tag the king of
random on February 4th which is exactly
one week from today I’ll look up
everyone who’s used the hash tag the
king of random and choose three of you
to get a blow
have fun making and sharing this project
and if I choose you as a winner on
Wednesday I’ll send you a private
message work out shipping details then
ship it to your house for free wherever
you are in the world I appreciate you
for supporting and sharing my videos and
I’ll talk to you in the next project
video bye
