This measuring cup is specifically created for liquids. The container is made of glass, so you can see what the liquid is at. It will be 6 inches tall and the base of it is 4 inches wide and 4 inches long. In order to use it, you first open the hatch at the bottom of the measuring cup, pull the arm at the end, sucking all of the liquid into it. Close the hatch and snap it shut. When the hatch is shut and all of your liquid is inside, you then push the handle down until you can't push it any farther. Make sure not to push it any farther after it’s snug and tight. After finished measuring your liquid you put your cup/container underneath of the measuring cup, open the hatch, and push the arm to remove the liquid into the cup/container.
