Brain teaser

Saw this brain teaser and wanted to share. Can you figure it out?

You have eight balls all of the same size.  7 of them weigh the same, and one of them weighs slightly more.  How can you find the ball that is heavier by using a balance and only two weighings?


  1. Ooh, quantitative decision making...too early to do that. lol

  2. I know the answer, but that's because my tai chi teacher taught it to us. So I won't ruin it for the other readers who may want to take a crack at it :)
