Using the metal handle, this Mac Funamizu's creation can show whether the flask is empty or full. Dubbed as the Pitch♪er, it's inspired from xylophone sound by having a built-in metal handle that works as a tuning bar and produces different sounds, when struck on the surface of the pitcher, to indicate if the pitcher is filled, half filled or empty.
The tone of the tuning bar is the same as that of the pitcher body with no water. When the pitcher is not empty, it makes a higher tone than the handle.
