Introduction: Portable Fort-in-a-Can

Picture of Portable Fort-in-a-Can

Hello everyone! have you ever been in a situation where you're really wanting to make a fort but have no materials? like in a movie theater, at the mall or even in your car? Well now you can, with the ALL NEW portable Fort in a Can! 

Step 1: Parts and Tools

Picture of Parts and Tools


RC Motor assembly (motor, ESC, battery and servo tester)
Motor Mounting Hardware
Large Coffee Can
Large Bed sheet
6" Fan Blade

Optional: mp3 speaker


krazy glue
dremel tool

NOTE: using a regular fan motor and such a small fan blade will not make this work. i used an rc outrunner (running at approx. 12000 rpm) in order to achieve the amount of airflow possible to inflate the sheet.

Step 2: Modifying the Coffee Can

in order for this to work properly the motor,fan assembly need to be in the exact center of the coffee can. I discovered a little trick in the modifying process in order to achieve exact center. on most coffee can lids there is a small dimple int he exact center, place it on the bottom of the can as shown and mark a dent in the metal with a screwdriver. 

Next, take the motor and measure the spacing between the mounting screws then transfer that information onto the bottom of the can using the dent you made as a center reference point.

Step 3: Modifying the Coffee Can Continued

make markings on the bottom of the can for air intake holes and one on the side for the motor wires then cut/drill out those shapes with a dremel tool

Step 4: Fan and Motor

Now take the fan blade and put some krazy glue into the space where the motor shaft will be. then insert the motor shaft and wait a few minutes for the glue to dry

Step 5: Final Assembly!

1. take the motor/fan and mount it to the bottom of the can with the mounting screws
2. use krazy glue to attach esc and battery on the outside of the can
3. solder all electronic components together

Step 6: Now You Have a Fort for Anywhere!

now you just stuff the sheet in and youre ready to make a fort literally anywhere! 

the sheet inflates enough to just fit me lying down (im 6'3") with another person beside me

Great! (admittedly, I clicked on this as I thought it said 'fart in a can')

PATSY001 (author)eyewalk2013-09-29

I as well thought it was "fart" and not "fort"

Very cool. I remember making something like that for myself as a kid by setting up a sleeping bag in front of a fan. If I can get the stuff together maybe I'll do it up as an instructable too.

I would suggest looking into a small blower fan. They are not expensive and put out a much higher volume of air at a lower noise level. Love the idea of the portable fort... you could sew up something and likely market it with great success.

Love that... always wanted to tell people about that!!!

Haha JensKidsAdventures,
I am in the same boat. I flipped through every step becoming more and more convinced that "fort" must mean "fan/motor/electrify your coffee can /etc" in Willy's native language. and then right at the last minute it became a fort. I like the wind tunnel effect too, my least favorite part about an indoor fort is how hot and stuffy it can be. Finally, somebody added some A/C!

Not at all what I was expecting, until I realised I'd misread it and it actually said 'fort' in a can. I thought it was just going to be a can of beans.

Sorry, I don't get the idea: Why would ppl. want to inflate their duvet cover?

WillyWatts (author)2013-08-04

Trust me you can't use a smaller fan ahaha

ultrakill (author)2013-08-04

if you used a less porous material, and sealed it round the tin, you could probably use a smaller fan... have you got any waterproofing stuff for tents? it might do the trick...

poofrabbit (author)2013-08-04

Love this! Very neat idea, wish I had one as a kid.

In Elementary school, we had an astrologist come by with this big black sheet and blew it up using that. And we would all pile in and sit on the ground, while he demonstrated the star constellations and so on. It was loads of fun. This could be used in similar fashion!

Speidumb (author)Boygasmo2013-08-04

I'm pretty sure you meant Astronomer. Astrologists tell the future by looking at the stars, astronomers blow up big inflatable bubbles and tell kids about stars.

zebede5 (author)2013-08-02

Haha, love the idea, but i would LOVE to see you get this into a movie theater:P

JensKidsAdventures (author)2013-08-02

That is such a unique idea. I had no idea where you were going with it until the very end. Glad I read through to the finish.

thank you very much :)

WillyWatts (author)2013-08-02

Well the thing is I had to inflate it from the outside or else I couldn't film properly. But the fan speed controller cord is long enough so that you can crawl in first then inflate it while you're inside!

Dominic Bender (author)2013-08-02

Doesn't it deflate when you crawl into it? Interresting idea, though, thanks for sharing!

OMG, it's a bouncy castle!
