Paper Rockets That Fly 300 Feet

00:00:06if you built this rocket launcher from a

00:00:10previous project then you’re going to

00:00:11need some rockets in this video you’ll

00:00:14learn how to make these durable

00:00:15high-pressure rockets for about five

00:00:17cents each


00:00:33it’s a beautiful day so I’m taking this

00:00:36project outside on my patio I’ll get

00:00:39started by placing my rocket launcher

00:00:40with the barrel overhanging this ledge

00:00:42I’m going to start making this fairly

00:00:44quickly so I’ll plug in a hot glue gun

00:00:46to get it warming and start cutting this

00:00:48piece of paper right down the center 1/2

00:00:50will act as a spacer and the other half

00:00:52will form the rocket body let’s roll the

00:00:54first half tight around the barrel and

00:00:56tape it to itself and then take the

00:00:58other piece and wrap it the same way now

00:01:00we have two layers to this roll and

00:01:02we’ll need to position them so the top

00:01:03layer is overhanging just enough to

00:01:05press the sides inward from four

00:01:07directions all the paper on the tip is

00:01:09overlapping so it’s time to add some

00:01:11electrical tape start at the base of the

00:01:14top layer and wind in a circular fashion

00:01:15until it’s wrapped all the way up the


00:01:18this tape is very durable and perfect

00:01:20for holding these rocket bodies together

00:01:22under pressure when we get to the tip

00:01:24let’s wrap several layers of tape over

00:01:26the top and around the sides because

00:01:28this is the part that’s going to take

00:01:29the most abuse when that’s rounded and

00:01:32smoothed out we can wrap one more layer

00:01:34down the rocket body ending right back

00:01:35where we started this rocket will need

00:01:38some fins so I’ve ripped a piece of

00:01:40cardboard off a box and when I’ve

00:01:42squared up the edges a bit I’ll make a

00:01:43mark a third of the way up the body and

00:01:45another mark as wide as the barrel using

00:01:48a straightedge we can connect the dots

00:01:49and cut the

00:01:51now we have a template to make more fins

00:01:53and we’ll need four so let’s trace those

00:01:56out and begin cutting this way we’ve

00:01:58managed to keep the fins all about the

00:02:00same size they’re not perfect but hey

00:02:02it’s not like this is real rocket


00:02:04okay hot glue goes on this end and then

00:02:07presses into place flush with the base

00:02:09of the electrical tape when it’s

00:02:11hardened rotate the fin down and place

00:02:13another one on top I’m trying to make

00:02:15all the fins relatively symmetrical and

00:02:17this seems like a good way to get the

00:02:18job done okay we’re done with the hot

00:02:21glue so we can unplug that and this

00:02:23rocket is nearly finished I’m adding two

00:02:25wraps of tape just over the tips and

00:02:27when I smooth it all out it’s finished

00:02:29there’s just one thing left to do and

00:02:31that’s remove the inner layer of tubing

00:02:32this will create a slight gap making it

00:02:35easier to load the rocket I’m also

00:02:37adding extra tape to the bottoms of the

00:02:39fins to ensure this little rocket is

00:02:41super durable I think it’s ready to test

00:02:43out I’ll use my air compressor to charge

00:02:46the system to 135 psi and once we close

00:02:49the ball valve we can disconnect the air

00:02:51hose and now we’re completely portable

00:02:53okay I’ve got my rocket set and the

00:02:55neighborhood is clear winds are calm so

00:02:58it’s time to fire that’s a good shot and

00:03:01land it all the way down at the end of

00:03:03the street this is an insane amount of

00:03:05pressure for a paper rocket to a stand

00:03:07and would blow most little rockets to

00:03:09bits but this design seems to get the

00:03:11results because even with all the

00:03:13pressure they shoot amazingly straight

00:03:15and they can be used again and again I

00:03:18still can’t get over the distance these

00:03:20cheap little things can cover this one

00:03:22just went 300 feet and flew over my

00:03:24house I’m really happy with how this

00:03:26project worked out and at a cost of

00:03:28about 5 cents each I feel like I’ve got

00:03:30my money’s worth that’s it for now if

00:03:33you liked this project perhaps you’ll

00:03:34like some of my others check them out at

00:03:36the king of random calm
