If you are lucky enough, while your travel to Russia you can manage to buy vodka in a plastic bag. More than that this plastic bag can be used as a medical dropper.
It is made in China so the price is very low just 22 cents for 16.9 fl. oz. pack.
What is the purpose of this? Probably some people enjoy drops of vodka coming to their blood and then directly to brain, omitting a stomach.
