    Lightning is a powerful force of nature. In fact,  a lightning strike carries millions of volts（伏特）of electricity. Scientists say a bolt of lightning strikes somewhere on Earth every second. That is a lot of energy!

Think how wonderful it would be if we could capture lightning and sell it in a bottle. Sadly, that is not something you or I can do, at least not yet.

The phrase "to catch lighting in a bottle” means capturing something powerful or difficult. Then you are able to control it and perhaps show it to the world. This is where the "bottle” part is important.

We can also use "to catch lightning in a bottle" to describe an extremely difficult or unlikely success. In the world of sports , players and teams have also been known for catching lightning in a bottle. Anything physical that is "lightning in a bottle "can be described as a rare achievement. Climbing the top of Mount Everest is considered a rare achievement of endurance（忍耐力）.

Language experts do not know exactly where this expression comes from. Some say it may have started with Benjamin Franklin---the American diplomat, businessman and inventor. Benjamin Franklin is known for a scientific experiment involving electricity and lightning. As the story goes, Franklin once flew a kite in a lightning storm. He had hoped that lightning would strike the kite as it flew high in the sky. He thought the electricity would travel down the string to a metal key at the bottom. Then the plan was to catch the electricity in a glass jar, but that didn't happen. However, it did lead to the invention of the lightning rod and the understanding of positive and negative charges.

So, you can’t catch real lightning in a bottle. But hopefully, during your lifetime you'll have the experience of catching a little of your own lightning in a bottle・
