This might be the most talented street artist I’ve ever seen, and it involves playing the beautiful song Hallelujah by using only his fingers and a set of crystal glasses.
The way this works is by moving a finger along the edge makes the glass resonate, that then causes the air inside the glass to vibrate…. creating a sound wave.
Now, when you change the amount of water in the glass it changes the sound dramatically.
By adding more or less water you can easily change the pitch, which is why he can play that song. Check it out…..
Hallelujah is such a beautiful song! Let us know what you think and make sure to give this a share on Facebook before you go.
