Surprisingly, they’re only powered by one single match head. In this project we’re using aluminum foil and a box of matches, to make the ultimate in desktop weaponry. Homemade, Matchbox Rockets. All we need to start this project is a box of matches, aluminum foil and a wooden skewer. I’m using these green “strike on box” matches, but the red ones will work just as well. Ok it’s time to get to work, and the first thing we need to do is grab a few of these matches and set them to the side, because we’ll still need a bundle of those, for our kit when it’s finished. Now amazingly, these rockets are only powered by one single match head. But they only work, if we get rid of the stick first. Of course that’s not much of a challenge as long as you have a pair of scissors. And if you try lining your container with something like a sock, the match heads won’t bounce out. Instead they just collect conveniently at the bottom. Here are all the match heads I got from this box, and to store them, why don’t we try using one of these soda cap containers made in a previous project? These things have all kinds of applications, so look for for how to make them in another project video. Alright, to start making our assembly kit we’re going to need a single bamboo skewer, and this template which I’m going to give you for free. Just look in the description for a link on where to get that. Transfer the marks from the diagram onto the skewer, then carefully cut the ends off, so when it’s modified, it looks like this. The next step is to tape the body template to a piece of paperboard, like this one I got from a cereal box. Make sure to cut the edges as cleanly as you can, because this is going to be our tracing template. The little square I’m cutting out now is the guide for tracing the rocket’s fins. And for those, I use aluminum foil tape I got at the hardware store. Each square will make one set of rocket fins, so cut as many as you want, then fold them “point to point” from both directions. Pinch them at the base and push your fingers together, so that when you crease them down it looks like a little x-wing. When you snip off the point at the very tip, the rocket fins are ready for application, and by now you should have an idea of how this is going to work. Now I made a whole bunch more and loaded them into the other side, of the soda cap container, so I have them on hand whenever I need one. Ok, let’s bust out the aluminum foil, and tear off a sheet to start creating the rocket bodies. I’m laying a sheet of paper towel overtop, then carefully folding the stack up 3 times, so it’s 4 layers deep and just a bit larger than the cardboard template. You probably figured out already that we’re going to trace around the edges, then cut the shape out of all the layers, at the same time. Normally the edges would stick together after the foil’s been cut, but you can see the paper towel solves that problem, and makes it super easy to separate. I tried making 13 pieces at the same time, and it actually worked, so you can see how quick and easy it is to make a whole stack in no time flat. And check this out, the assembly station is completely portable as well. I designed the patterns, and the template so they’d fit perfectly inside the matchbox, and you can see there’s a little place for the skewer in there as well. Now to finish our rocket factory the only thing left to do is make a small hole in the top of the box, about half an inch from the end. Now if we bring back any matches we saved from earlier, and add a candle, we’ve created a portable assembly station, that you could take just about anywhere. Alright, let’s get to work and build some rockets. Here you can see what the finished rocket will look like. It’s light as a feather, but surprisingly stable in flight. You might have noticed there are two markings on the template that indicate how to roll the body tube. With the skewer in position, place a single match head on top, and make sure it’s pointing upward, without any gaps. Now slowly and carefully roll the foil tube, as tightly and neatly as possible. When you get to the end, pinch the tube right above the match head, then push the foil down flat. There should be about half an inch of foil at the top, and this gets rolled toward the match head. The most important part here is crimping the tip with something like a pair of pilers. And you might want to crimp multiple times, and from different angles just to make sure it’s completely sealed. At this point, let’s attach the rocket fins we made earlier, by peeling off the sticky stuff on the back, then pushing the rocket body through the hole in the center. Just work the fins around until they stick firmly in place near the bottom of the rocket, and with that final step, you’re done. That’s how easy it is, to make a matchbox rocket. So while you’re at it, why not make a few more? I just made 13 of them, in about 10 minutes, and you can see they fit perfectly into the kit as well. So now you have the option of building rockets, on location, as you need them, or creating them all in advance so you can just show up and start shooting within seconds. The rockets get loaded by pushing the tapered end of the skewer into the nozzle, then twisting upward until it touches the match head inside. Push the skewer through the hole in the matchbox, and now if you push the box together, you can adjust the launch angle to whatever you need it to be. Now if you light a candle and position the flame just under the tip of the rocket, it will quickly warm the foil until the match head reaches its auto-ignition temperature. Which, you can see, shoots it off with an impressive amount, of speed and power. These rockets leave a satisfying trail of smoke when they blast off, but you do need to be careful because they get hot enough to burn your fingers, and put scorch marks in your carpet. Now of course the safer option is to launch your rockets outdoors. But you’ll probably find the flame on the candle won’t hold still in the breeze. I use a wind resistant BBQ ignitor to keep a steady flame, which you can see works pretty well. These rockets shoot from the front porch all the way to the street, and in some cases up to 40 feet away. So it’s important to use common sense, and avoid the temptation to point them at people or property. Well now you know how to turn a box of matches and some aluminum foil, into a fully portable rocket factory, so you can manufacture and launch, your very own matchbox rockets. That’s it for now.

I’ve been playing with different prototypes for matchbox rockets for over a year. So I’m really excited, and proud, to finally be able to present this design. I’m also excited to give you the template I made, for free. You can click right here to download the template right now, and if you try making some of these, I would love to see you post pictures on my Facebook page at www.facebook.com/thekingofrandomfanpage. The link for that’s in the description. Before you go I just want to tell you I think you are awesome. I read your comments and I watch to see if you like my videos, because it really means a lot to me when you do. Please have fun with this project, be safe, and keep an eye out for my next project video. I’ll talk to you then.
