Paper Rockets That Fly 300 Feet

if you built this rocket launcher from a
previous project then you’re going to
need some rockets in this video you’ll
learn how to make these durable
high-pressure rockets for about five
cents each
[Music]
it’s a beautiful day so I’m taking this
project outside on my patio I’ll get
started by placing my rocket launcher
with the barrel overhanging this ledge
I’m going to start making this fairly
quickly so I’ll plug in a hot glue gun
to get it warming and start cutting this
piece of paper right down the center 1/2
will act as a spacer and the other half
will form the rocket body let’s roll the
first half tight around the barrel and
tape it to itself and then take the
other piece and wrap it the same way now
we have two layers to this roll and
we’ll need to position them so the top
layer is overhanging just enough to
press the sides inward from four
directions all the paper on the tip is
overlapping so it’s time to add some
electrical tape start at the base of the
top layer and wind in a circular fashion
until it’s wrapped all the way up the
body
this tape is very durable and perfect
for holding these rocket bodies together
under pressure when we get to the tip
let’s wrap several layers of tape over
the top and around the sides because
this is the part that’s going to take
the most abuse when that’s rounded and
smoothed out we can wrap one more layer
down the rocket body ending right back
where we started this rocket will need
some fins so I’ve ripped a piece of
cardboard off a box and when I’ve
squared up the edges a bit I’ll make a
mark a third of the way up the body and
another mark as wide as the barrel using
a straightedge we can connect the dots
and cut the
now we have a template to make more fins
and we’ll need four so let’s trace those
out and begin cutting this way we’ve
managed to keep the fins all about the
same size they’re not perfect but hey
it’s not like this is real rocket
science
okay hot glue goes on this end and then
presses into place flush with the base
of the electrical tape when it’s
hardened rotate the fin down and place
another one on top I’m trying to make
all the fins relatively symmetrical and
this seems like a good way to get the
job done okay we’re done with the hot
glue so we can unplug that and this
rocket is nearly finished I’m adding two
wraps of tape just over the tips and
when I smooth it all out it’s finished
there’s just one thing left to do and
that’s remove the inner layer of tubing
this will create a slight gap making it
easier to load the rocket I’m also
adding extra tape to the bottoms of the
fins to ensure this little rocket is
super durable I think it’s ready to test
out I’ll use my air compressor to charge
the system to 135 psi and once we close
the ball valve we can disconnect the air
hose and now we’re completely portable
okay I’ve got my rocket set and the
neighborhood is clear winds are calm so
it’s time to fire that’s a good shot and
land it all the way down at the end of
the street this is an insane amount of
pressure for a paper rocket to a stand
and would blow most little rockets to
bits but this design seems to get the
results because even with all the
pressure they shoot amazingly straight
and they can be used again and again I
still can’t get over the distance these
cheap little things can cover this one
just went 300 feet and flew over my
house I’m really happy with how this
project worked out and at a cost of
about 5 cents each I feel like I’ve got
my money’s worth 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
