3 Minute USB charger!!!

I made this charger whill on my bed just playing with a USB cable then an idea hit me this is how to make it:

Things Needed:

Usb cable extender( The thing with the female and male plug on it)
Battery Holder it must hold 3 AA battreis( you can find them inside some torches)
Scissors
Tape
And 4 AA batterys ( one for spare)

Step 1 Cut it

Now cut the female plug( the one that plugs into your computer) off and strip the wire. Now to find the - and + cables inside the usb extender, put one on your toung (DON'T WORRY IT WILL ONLY TINGLE NOT SHOCK AS IT IS DC CURRENT) and then touch the other ones. Norrmaly it is black and red so test those ones first.
