Earlier tonight, I was talking to my friend and I happened to place my cell phone on top of a commercial coffee maker (a Bloomfield "Koffee-King") that I had in my garage. To my surprise, the stainless steel lid on top of the coffee maker where you pour the water in began to buzz with the GSM signal.
Now I'm pretty sure most are familiar with the buzzing sound one gets from a cell phone placed near a radio or amplified speakers but a coffee maker wouldn't have a speaker or amplifier in it to pick up the signal and translate it into sound. Somehow, the signal was reacting with the metal parts of the coffee maker and causing it to vibrate and make the sound.
I later took a video of this. The noise is somewhat faint but could be heard. (Ignore the air raid/tornado siren ringtone)

Could anyone explain this ?
