Introduction: Mini Hovercraft? and Fan (mostly Fan) But Cool

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
expiriment with batterys (start with three)
the screws are stableizers

Step 4: Sealing

    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.

    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

    If you reverse polarity your fan will also go reverse.

    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.

    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)
