A natural gas company in Great Falls, Montana, wanted to educate consumers. So it printed 25,000 scratch-and-sniff cards to show how a gas leak would smell. Then the company tossed some of the cards. As they were crushed in a garbage truck, the gas smell filled the town.

The new boom in natural gas from shale has changed the energy economy of the United States. But there's another giant reservoir of natural gas that lies under the ocean floor that, theoretically, could dwarf the shale boom.

No one had tapped this gas from the seabed until this week, when Japanese engineers pulled some up through a well from under the Pacific. The gas at issue here is called methane hydrate. Methane is natural gas; hydrate means there's water in it. In this case, the molecules of gas are trapped inside a sort of cage of water molecules.
