Friday gold puzzle – can you crack it?

Here’s a bit of Friday gold bar fun via an interesting puzzle sitewe found…

You have nine small bars of gold, eight of which weigh 100 grams, the ninth gold bar weighs 110 grams.

The gold bars have got mixed up and being identical in appearance it is impossible to tell which is the 110 gram bar.

Fortunately you have a set of balance scales. But the scales can only be used twice, so using the scales to weigh two combinations of bars, how can you find the heavier bar of gold?
