How to Make Rocket Igniters (Electric Matches)


for this video I’m going to show you how
to make a handful of remote-controlled
electric igniters from things you
already have around the house it’ll
ignite fireworks a flame from a distance
or launch your homemade rockets with
this simple press of a button to start
this project you’ll just need a book of
paper matches some tape and an old cell
phone charger chances are you have a
spare charger somewhere in the house but
if not you can easily find them at
thrift stores for about a dollar now get
to work with a pair of scissors and
carefully chop the head and charge
controller off the cable then cut it up
into smaller pieces around two inches
long if we remove the outer jacket you
can see there are two insulated wires
inside made of very thin stranded copper
wires and for this project the thinner
the wires are the better the igniters
will work now we don’t need the outer
sheathing at all so go ahead and pull
the wires out and strip the other ends
down about half an inch
carefully single out one copper strand
from the bundle of wire and pull it off
to the side and now the other frayed
wires are all garbage so just twist them
together and use a pair of scissors to
snip them off the base now let’s take a
close look at the other wire if it has
nylon cording mixed in with the copper
strands you need to get rid of it and
the most effective way to eliminate it
is to lick it with a flame from a candle
or a BBQ igniter now hold the two cables
side-by-side about a quarter of an inch
apart then twist the bridge wire from
the first cable so it binds together
tightly and meshes in with the other
strands this will ensure the bridge wire
has great electrical contact and should
prevent it from unraveling to hold the
wires in place simply lay a small piece
of tape on the table so it’s facing
sticky side up and press the wires down
into the center now make sure the bridge
wire is poking out around a quarter inch
from the top then bend the excess wire
back and press it down beside the wires
on the inside
all right the igniter leads are
completed so let’s take a quick break
from all that and spend some time
modifying the match heads take the
matches one at a time and carefully
slide them down the edge of a sharp pair
of scissors you can see it scores a very
small groove right down the center of
the tip now bring back the igniter leads
and line the bridge wire up with the
groove in the match head and secure it
firmly in place by wrapping one side of
the tape tightly over the base of the
match then reinforce it again by firmly
wrapping the other half of the tape the
other direction for one finishing touch
it’s good practice to burn the nylon
strands on the igniter leads as well
then twist them together tightly so
they’ll make better contact at this
point your electric matches fit
and ready to go to work to test them out
I tried connecting alligator clips to
the leads of the igniter then running
the wires to two 9-volt batteries in
parallel now all it takes for ignition
is the press of a button to complete the
circuit or in this case a touch of the
wires to the battery terminals the match
is light off because when the circuit is
completed over six amps of electrical
current surge through the tiny bridge
wire on the top and the electricity gets
the wire so hot it ignites the chemicals
in the match head causing it to burst
into flames and you can see that all
happens very quickly now just for fun I
got an old n64 controller and converted
it into a rocket launch controller so
now I can launch homemade sugar rockets
with the press of a button look for how
I made this in another project video
well now you know how to mass produce
electric igniters with junk you probably
have lying around the house by the way
if you try using different colored tape
you can give your igniter is your own
custom touch and if you can’t find paper
matches wooden matches will work just as
well well that’s it for now if you liked
this video perhaps you’ll like some my
others check them out at the king of
random comm hey guys I just want to let
you know how excited I am to have you
join me for these projects I constantly
feel your support and I’m always looking
for new ways to give back so this time
I’ve got 125 dollars that I want to
divide randomly between five of you so
hang on and I’ll show you how to work
this video is sponsored by the good
people at harrys.com and I told you back
in January that I started using their
razor so I could test them out on myself
but I just ordered a pack of 20 more
blades for 25 dollars and they came with
free shipping if you do the math on that
that’s only a dollar 25 a blade which is
way better than the $4 a blade I was
paying before I find my razors lasts
between two weeks to a month so these 20
blades mean I’m pretty much covered for
the next couple of years now for
watching this video Harry’s will give
you five dollars off any of their
products to try it out go to harrys.com
right now and enter the coupon code the
king of random when you’re checking out
and it’ll automatically take five
dollars off your order you can get a
razor moisturizing shave cream three
razor blades and free shipping to your
door for only $10 break it down and
you’ll see why that’s a really good deal
the Winston is the 25 dollar set and
it’s actually the one that I use so I
thought it would be fun to pay for five
of you to get one as well so click the
link in the description and enter your
email address and one week I’ll randomly
pick five of you from the list and send
you $25 whether or not you buy anything
from Harry’s it’s just another way for
me to say thank you and give back thank
you for watching
sharing and supporting my projects I
will see you in the next project video
talk to you then
