Shot glass
From Freepedia
Traditionally, a shot glass was a small, thick glass designed to measure one ounce of liquid, usually liquor, to be either drunk straight, or poured into a mixed drink. Markings, if any, indicated the quantity of fluid at different levels.
Today, the size can vary, but still, the intention is generally to pour a specific amount of liquor. Markings now are more likely logos of organizations, e.g., restaurants/bars, or sports teams.
The most common shot glasses in the United States are of three sizes:
"single shot"- 1.5 fluid ounces (~44 mL)
"double shot"- 3.0 fl. oz. (~89 mL)
"pony shot"- 1.0 fl. oz. (~30 mL)
