USB Grass Charging Station

One day, i've see that on internet: http://www.geeky-gadgets.com/grass-charging-valet/ .It is a charging valet for electronic stuff.
But 30$ is really not cheap for that. Now, i will show how to do it from yourself for less than 3$.

You will need those things to make it:
- sinthetic grass
- usb port
- a container (the one you want)

First pass the usb into a hole of the container

Then, just put the sinthetic grass over it.

Now your electronic stuff is ready to charge and you have save 27$ for it. Enjoy it!
Oh, and thanks voting me for the usb contest!

This varient as multiple branch for charging multiple thing at the same time.
You need the same stuff for doig it except that the container is replaced by a strawberry jar and, of course more usb plugs.
