I don't care what you are doing right now. I want you to do this, and please do it exactly as I say it.
You need a MP3 player with earphones.. keep it ready connected to the PC.
Download this MP3 and copy it to your MP3 player.
Get out of your PC and go to some silent place.
Close your ears, hold your earphones as tight as possible.

WARNING: This will NOT be pleasant without your earphones. So, I reckon you NOT to try on Speakers before trying it on earphones. It is upto you how you build your own surprises !
