You have 8 identical-looking balls, but one is heavier than the others.
You have a balance scale and can use it only twice. How can you find the heavier ball?

You group them into 3-3-2. First, weigh 3 vs 3. If it's a tie, the heavy one is in the leftover pair. If one side goes down, the heavy ball is in that group of 3 then you just weigh 2 of those balls to find the culprit!
