Vodka is a kind of drink that is made from water and something called ethanol. Ethanol is made from stuff like potatoes, wheat, corn, or rye.
To make vodka, people take a lot of those plants and mix them with water. Then, they heat up the mixture to make the ethanol come out of the plants. The water and ethanol mixture is then filtered to make it clear and smooth.
Vodka doesn't taste like anything because it doesn't have any added flavor. That's why some people like to mix it with other drinks or add fruit to it.
When you drink vodka, it goes into your tummy and then into your blood. Vodka can make you feel a little bit funny or silly, especially if you drink too much of it. That's why grown-ups need to be careful when they drink it.
