Introduction: Air Fort

Picture of Air Fort

This is a quick Instructable on how to create an Air Fort. An Air Fort is a fort that is supported completely by air.
Air forts also have a green side. The fort uses very little air so it does not take a large fan to keep it inflated. The low power fan keeps the fort very cold. It is almost like a mini air conditioned room.

Step 1: Supplies

For this Instructable you will need:

A bed
A sheet larger than your bed(I use a sheet from my parents bed).
Clamps(to attach blankets to the bed).
Tape(duck tape or packing tape work best).
A fan

You do not need the bed or clamps if you don't have them. I recommend using a bed because it is easier but if you want you could just tape the sheet to the floor.

Step 2: Step 1...The First Real Step

The first step is to take your sheet and lay it out on your bed (or floor). Next set your fan up on one side of your bed.

Step 3: Tape!

Next, take the end of the sheet and attach it to the fan using tape. Look at the picture for help.

After you attach your sheet turn on the fan. The fort should inflate a little.

At this point you should have the sheet only attached to the fan and the fan turned on.

Step 4: Leaks...

Then, climb inside your fort. Look for where the air leaks out. Take your clamps and close all the leaks (it may help if you tuck the sheet under your mattres).

Step 5: Almost Done! Step 4

The last step is the hardest. You must add a door. Doors are very tricky.

Undo one of your clamps. Instead of attaching the clamp to the bed just attach it to the sheet. The weight of the clamp will hold the sheet down.

If anything was unclear just let me know.

I remember one year in 3rd grade when my teachers made a giant inflatable blob out of trash bags, duct tape, and a fan. It had a TV inside it. My whole class got inside it and watched "The Polar Express" and drank hot chocolate... Fun times.

whoa do u have pics????????? :)

bwool1 (author)Mistystar5192011-07-09

I don't have pics of that, since I was only in third grade, but I recently made a clear plastic inflatable bubble in my backyard, and I have pics of that. It's made of a thin painting tarp, and held down with bricks. It's not as big as the one that I got to watch Polar Express in, but it was fun.

hleon (author)2009-04-20

Dude this thing is wicked!! I built mine on the floor and used my text books to hold the sheet down!

mr. clean (author)2009-03-18

i too used to do this when i was young but instead of one sheet i would use two and duct tape the sheets together (i have a very bigh room) it would take three fans to get it really full, and i just pinned the sides down with books on the floor.

Allowance10 (author)2009-02-24

The pictures are in order. You turn on the fan so you can see where the leaks are.

the_burrito_master (author)2009-02-21

your pics are mixed up pic 3 should be pic 2.

Other than that it's great!

I used to do this all the time as a kid with my window fan in the summer (my bed was right next to my window and the window was low to the ground so it was the perfect height). Keeps you very very cool on those warm nights. I'd just prop some pillows or stuffed animals around the edges of the blanket to hold it down.

Allowance10 (author)2008-10-26

Thanks for the comments...I will try the plastic idea.

Lftndbt (author)2008-10-26

We do this on hot summer nights. Another idea is to use the duvet. Spread it out, unbutton the base attach it to fan and there you have it. No leaks, perfect lil' tent. Very nice on hot nights.

Dorkfish92 (author)2008-10-25

cool. I made one once. If yuo goto Lowes or Home Deopt, ask them for their plastic liner stuff for your car.( It's used to put plants in the trunk of your car) That stuff is really lite plastic so it works pretty well.

hmmm cool! My instructable does roughly the same thing, but to make a sauna...
