How to make a USB fan

Hello everyone this instructable is fun to make.
I made it in about 2 minuts.
But there is not enough power from the USB port so the fan spins fast but not fast enough.
sorry about that but it produces enough thrust to move a piece of 4mmX4mm paper.
I used some images from the web because i couldn't take the right photos.

5 volt fans are on sell online :)

Here's my question - A 5 volt fan would draw enough power from a standard USB port. However, will the 5 volt fan be able to draw a similar amount of power from a USB hub? Probably yes, you would think, if the hub were running on AC power. So, would two 5 volt fans draw 5 volts each from a two port USB-powered USB hub?

Undortunately...old pc fans are 12v...atleast what i found

i know, but i have heard of a dc step up transformer so you could use one of those for the power
