Rocks become smoother as rough and jagged edges break off. Students run a model of this process by shaking sugar cubes and gravel together in a plastic container. The sugar cubes become smoother as their edges break off when they collide in the container.
By Diane Alter, Contributing Writer, Money Morning -. Gold prices today (Friday) climbed $18.90, or $1.66%, at $1,158.90, which was a six-week high for the precious metal. Gold prices today climbed after the release of the latest Federal Open Market Committee (FOMC) minutes.
Prices need money, however. And the Sterling gold price also hit record highs two years ago today. Peaking at Â£1194 in the spot market, gold was fixed at a record high of Â£1182.82 per ounce on 6th Sept 2011. But the peak gold price in both Euros and Swiss Francs didn't come for another 12 months. Japanese savers got their peak price in April 2013.
