Seesaw
A seesaw (also known as a teeter-totter) is a long, narrow board suspended in the middle so that, as one end goes up, the other goes down.
In a playground setting, the board is balanced in the exact center. A person sits on each end and they take turns pushing their feet against the ground to lift their end into the air. Playground seesaws usually have handles for the riders to grip as they sit facing each other.
In dog agility, the board is off balance so that the same end always returns to the ground after the dog has run across it.
Seesaws are also used in acrobatics.
