[TRICK] Headphone to Microphone
Did you ever knew that your headphone could be turn into a microphone?
Well, here's how to do it:
1. Plug your headphone in the microphone port (afaik, any headset should work but not all).
2. Open your Sound Recorder (Start>Programs>Accessories>Entertainment>Sound Recorder).
3. Press the record button and make sounds.
4. Then look at the graph movements, means that you're producing sounds.
Note: Never tried this before, hahah! :P
Have fun!
