Seltzer bottles!

It's theme day and the theme is "water"! These are seltzer bottles, empty at the moment, but which can be filled with carbonated water, also known as sparkling water, plain water into which carbon dioxide gas has been dissolved. Nowadays hardly anyone uses these classic bottles, but there are still a few stores around town where you can take yours (if you still have one...) to be filled to add to white wine to make wine spritzers. Otherwise, most people opt to use already the Serbian bottled naturally sparkling water, Knjaz Miloš (Kuh-NYAZ MEE-lush), named for a Serbian prince, which comes from mountains near Arandjelovac (Ah-ron-JEL-o-vats). Quite a mouthful of words to pronounce today!
