Hey Everyone! Here are the detailed plans for the Jet pack project. Keep in mind that this is just the way I did it. You an always tweak things to suit your movie needs and of course improve my design. If you do make a cool jet pack or figure out an improvement let us know. We might even feature you in our special monthly podcast.

Shopping List

1. An old rigid frame backpack. (I got mine at a flee market for $7 dollars.)
2. A fire extinguisher. (Only needed if you want the blast off smoke)
3. A green screen. (check out the Quick Tip at the end of Episode #1)
4. Spray Paint (Whatever colors you want! I used flat black, chrome and primer gray)
5. Some epoxy.
6. Nuts and bolt. (Check the junk drawer in the kitchen.)
7. F.A.A. flight permission.
8. 45 degree PVC joint (1/2" diameter) (Only needed if you want the blast off smoke)
9. 1.90 degree PVC joint (1/4" diameter) (Only needed if you want the blast off smoke)
10. 1/2" rubber grommet. (Only needed if you want the blast off smoke)
11. A bunch of plastic junk! (This is where the real creativity comes in. Go to a Junk store or garage sale and just look for stuff that might look good as jet pack parts.)

Here's what I used:

  • 2 cardboard tubes
  • A plastic paper tray (that sits on a desk)
  • A plastic paper tray (that mounts to the wall)
  • An old cartridge from a slide projector. 2 plastic file dividers. (kind of look like bookends)
  • 2 plastic hide-a-key compartments with hinged tops. (I mounted the other junk to this so I could lift up the shell and have access to the fire extinguisher.)
  • Some wire mesh I got at an art store.
  • A "danger flammable liquid" sticker I got from my friend who works at my local hardware store. (Thanks Elizabeth!)

Step 1: Cut the Frame

Building this prop is not rocket science, even though you're building a "jet pack"�. Sorry folks, I save all the best jokes for the show. Chances are you"re not going to find the exact backpack I did, and your "plastic junk"� is probably going to be a bit different too. So keep in mind these plans are just the way I put mine together. The bottom line, we want this thing to look cool. The first thing I did was cut a part off the frame of my pack. I wanted it to be more streamline, so I cut off these pieces with a rotary tool.
<p>I saw that episode!</p>
<p>Does this thing even fly ?</p>
Was that Oceanic Flight 815 he went past?
Niiiiiice, I see what you did there.
Mythbusters is awesome!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
note that he said that it's a prop
That works good! Better then i expected for $30! How high did he get?
(sniff,sniff) How could you?
two fier extinguishers some pvc pipe a metal frame back pack some string pvc two nozles made of pvc and a bit of patientce and it might be possible <br> <br> <br>try e how they might have your answer if you realy want to put your life and dreams on the line.
Wait... It doesn't even fly?

Do you think that you could make me one and I buy it from you???????????????????????????????????????????
Do you think i could order your jet pack online
this is a very good example of Albert Einsteins quote: "things sould be made as simple as possible, but not any simpler"
actually the fire extinguisher package tells how long it lasts.
little did he know that he was going to become extremely famous and go to sundance. Ahh hes so young.
funny vid
I enjoyed it. BUT, it didn't really show the whole green screen process.
I loved the video, very-umm, interesting?
I know me to
stupid. post a real one.
there's a f'ing puppet.....my....god....
got to love the 2ed pic on the frist page
I liked the way your jetpack looked, but the editing on the movie could have used some work.
Great Instructable and video. Although I hate to admit it, I kind of enjoyed the stupid cliches.
i agree about the length of the video...zaniness is great...but boredom kills also...don't know if it's an encoding issue...but all of your measurements are coming up as complete junk (1 �¼â�� diameter)...and a lot more of that gobbledygook is interspersed throughout.. i used a similar method to make a holloween mask a few years ago...used a fire extinguisher piped out to some hoses coming out of the filters on a respirator....walk around and press the "trigger" to scare the crap out of people with "smoke" comming out of your face....i got covered in the powder they put in those things...and it was a little hard to breath immediately after firing...but it looked cool and that's all that matters right?
I like the concept, but not so sure about the style. The superfluous "zaniness" at the start grates like a bad children's TV program, and I'm guessing that if your audience are playing with dremels and fire extinguishers they aren't children. It improves towards the end, with a little more originality and fewer cliches, but remember the point of indy TV is that you don't have to be bound by the formulaic confines of actual TV. Use the fact that you can take a risk and try out something completely new without annoying the "network bosses". Finally, I skipped straight over the "break" in the middle- this is an Instructable, not a magazine show. As you don't need to put adverts in the middle, you might consider relegating unrelated material to the end or even cutting it for videos you post on Instructables. (But, of course, what you do with your videos on IndyMogul or elsewhere is of course your own business) Otherwise, nice job and keep up the good work!
Great concept.... video too drawn out.... I lost interesting at the "stay tuned" portion and almost stopped watching when the intro was longer than 5 seconds (I stayed because this was the first one).... You'll gain a viewer (and likely others) if the next one isn't drawn out ;)
Pretty funny, LOL good job!
