Tibetan singing bowl

The singing bowl works much like when you were a teenager at a boring adult event and you ran your wet finger along the top of your water glass. With the singing bowl, you tap the bowl to start a vibration, then run the stick around the top of the bowl. You can either hold the bowl atop your palm or place it atop a pillow. The bowl is made from an alloy of several different metals, and the sound supposedly helps calm the mind. And it's kind of fun to play inside a large hotel with guests on either side of you.
