a craft made of plastic that floats (sorta)
my 2nd instructable leave comments!

Step 1: Materials!

solder ion
solder
9v battery clip 3 9v{radio shak}
wire tape
plastic can{me its a 6mm bb can}
fan (must be able to fit over can!){i got it from a computer}

Step 2: Solder Time

solder black wire on fan to switch
the other switch prong to black on battery clip
red go directly to + on battery

Step 3: Assembly

dill holes in plastic

I was like 10 when I made this I'm working with H2 O2 now xD but thanks I love people like you!!!

author

Isn't H2O2 hydrogen peroxide though? I worked with that when I was 10...

Great idea, never would've thought about using a computer fan for a hover craft... Please excuse my little rant below.

Dont know how long that fan will last if you keep using 3 9v batteries...
Every computer fan I have ever seen is rated to 12v, and 3*9v will give you 27v, which is twice as much as that poor fan is designed to use. Although I suppose that twelve volts would not proide sufficient air flow to actually lift the device.

On your next instructible please use the "macro" setting on your camera, these pics are really blurry.

 Umm, it doesn't matter which direction the fan is facing because you can just reverse the polarity of the wires.

author

Not with a brushless motor.

but its as clear as water it wont word just turn the whole fan over the computer fans specially brush less only go one way but if you flip it over you'll get the effect you all are looking for

dildo224 (author)LiquidLightning2010-02-02

Uhm when i reverse it the fan dont work?!?!?!

author

If you reverse polarity your fan will also go reverse.

author
flame boyyyy (author)Drasa2010-12-04

no it wont fool

author
Drasa (author)flame boyyyy2011-01-02

I meant fan, not motor. Sorry.

author
Drasa (author)flame boyyyy2011-01-02

Hmm, weird because all of my motors go reverse then. Also no need to call me a fool and break the "be nice" policy, I may be wrong.

author

now days no computer fans reverse polarity

author
Mudbud (author)LiquidLightning2010-03-16

 Yeah it does. some fans dont reverse polarity. :) 

author
Kasm279 (author)LiquidLightning2010-01-28

 the fan blades are shaped to spin a certain way

author
nawg (author)2011-03-09

PC fans have electronics in them so reversing polarity would be like reversing polarity on LEDs- It won't work. (some times it might turn in the same way no matter what the polarity. this is a protection feature on some fans)

Can this hovercraft lift a little weight?  I was thinking you could add the guts of  one of those $10 r/c cars on top.  You could have the drive motor power another fan and the steering motor move a little cardboard rudder right behind the drive fan.  R/C hovercraft!

"mini hovercraft" meh. Fabulous 27 volt battery idea? Priceless! heck, bypass the battery clip costs, and use the clip from one of the soon to be dead 9-volt batteries! Most can be cut with a pair of scissors. Others can simply be scored and snapped.

I wouldn't expect that 12v fan to last long running on 27 volts. Short tests shouldn't burn it out too quickly though.

author
learningmaster (author)LasVegas2007-05-24

mine wasint 12v it was a power supply fan

author
LasVegas (author)learningmaster2007-05-24

Fans in computer power supplies are 12V fans. Look at the label on the fan.

author
sci4me (author)LasVegas2009-12-20

i used a 12v fan with like 50v and it just barely lifted off da ground, but i didnt have a cup or anything.

Dude. Tell me you like 13 or something? Or just really board. lol Just kidding' I was wondering when someone would post a hover craft. Did you thing about doing something to reduce the friction between you craft and the surface it glids along? Like maybe using the lid from a pickle jar at the bottom so it would slide easer?

author

i was rely board and made somthing and it worked and i am 13

author

Well....... At least your not jumping off houses and blowing up kittens like I was lol

author

i havnt blown up kittens yet

author
yobwoc (author)The Red Button2009-08-06

Actually, there are already several hover crafts (none like this though) posted on this site.

To take up close photos, press a button on your digital camera that looks like a little flower. Hold a your picture button down half way to focus. Then press it all the way to take the photo. You still need to be about 6-10 inches from the object. if you want the photo object closer, try using your zoom. It won't affect the focus. Good luck and thanks for posting these instructions.

Can this really fly?

author
bylerfamily (author)awang82009-06-03

No,it is not supposed to fly,it is supposed to propel itself across water.

i used a hair dryer motor/fan and a 12v power supply.....

AznPanda (author)2009-02-24

>.> jeez i was reading the comments some are kinda mean :o Nice instructable but wouldn't 3 batteries be a bit heavy? O.o i might try this or i might make it into a fan... Or both O.O

Use a styrofoam plate instead of a jar.

author
he3r0 (author)2008-03-06

Neat idea, but please run a spell check before posting. also I would use lower profile (like maybe 1.5") plastic, square, "glad", food container (ask your mom about it, of g-f/b-f whatever)
