Cis forChopsticks
Chopsticks are used in many Asian cultures instead of a fork. They are just two sticks that you hold in one hand and use a slight scissor action to pick up food between the ends of the chopsticks.
If you have never used chopsticks before it can take some practise to be able to properly pick up your food. Most food that is designed to be eaten with chopsticks is cut into small pieces before it is cooked, so you don't need a knife while you are eating.
Gis forGlass (container)
A cup or mug is very similar to a glass. All three are used to drink from. Glasses are transparent so you can see what is inside, and mugs have a handle on the side to help hold them. People usually drink hot drinks from cups with handles.
