Given 8 oranges on the table, 7 of them have exactly the same weight and the 8th is a little bit lighter. You are given a balance that can measure oranges against each other and you are allowed to use the balance at most twice. How can you determine which one of the oranges is lighter than the others? Explain your answer!

Remark: All oranges look the same and the difference in the weight of the lighter orange is not big enough for you to distinguish it without using the balance. The balance doesn't have any weights or numbers. If you put some oranges on each side of the balance, you can only tell which side (if any) is heavier.

Present the answer in LaTex format: \boxed{Your answer}
