The length of the air column above the water determines the resonant frequency, and thus the pitch achieved. Tuned bottles may be struck (placing them in the percussion family), or blown (placing them in the wind instrument family, similar to pan-pipes). In the latter case, they are often known as blown bottles.
Platinum is a chemical element; it has symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name originates from Spanish platina, a diminutive of plata "silver". [7] [8] Platinum is a member of the platinum group of elements and group 10 of the periodic table of ...
The platinum-group metals [a] (PGMs) are six noble, precious metallic elements clustered together in the periodic table. These elements are all transition metals in the d-block (groups 8, 9, and 10, periods 5 and 6). [1] The six platinum-group metals are ruthenium, rhodium, palladium, osmium, iridium, and platinum.

As liquid is poured from a bottle, the air pressure in the bottle is lowered, and air at higher pressure from outside the bottle is forced into the bottle, in the form of a bubble, impeding the flow of liquid. [3] Once the bubble enters, more liquid escapes, and the process is repeated. [3] The reciprocal action of glugging creates a rhythmic ...
