A 108-year-old Message in a Bottle

    On November 30, 1906, George Bidder dropped a bottle from a boat into the North Sea. The weighted glass bottle sank almost to the sea floor, and then it move slowly for 108 years and 138 days.

    Its journey ended when Marianne Winkler found the bottle in 2015. Winkler was then on vacation on Amrum Island. She picked up the bottle when it was washed up onto the beach. She saw a piece of paper inside, but didn't break it open. She could tell that the bottle was old. So she didn't want to damage it.

    Finally she got the piece of paper out of the bottle. She found that the paper was actually a postcard. On the back of the card there was this message: The Marine Biological Association（海洋生物学协会） would pay a shilling（先令） for the bottle. A shilling was a unit of money that was used in Great Britain before the early 1970s.

    Winkler filled out the card and posted it. The association was surprised to get a postcard addressed to George Bidder, the president of the association from 1939 to 1945. The workers of the association searched on the Internet to find a shilling. They found one and sent it to Winkler as a reward.

    The message in the bottle was the oldest ever re-discovered. For this reason Marianne Winkler got a place in  “Guinness World Records”（吉尼斯世界纪录）. She broke the record for the oldest message in a bottle.

    Winkler's bottle was not the only one Bidder sent to sea. Between 1904 and 1906, he spent away more than one thousand bottles. He placed postcards inside them. The bottles were part of a research  project to map currents（洋流） in the North Sea. This was the best method at that time. But whether the association could get the bottles back depended on the people who found them. The association reported that about 55 percent of the bottles were returned. They added that the experiment was a success as it showed the east-to-west flow of the North Sea's currents.

    One day, my father and I were in line to buy tickets for the circus(马戏表演). And a family was standing in front of us.

    The family had eight children. Their clothes were not expensive but clean．The children talked about the clowns(小丑), elephants, monkeys and other things excitedly. It was their first time to go to the circus.

    The ticket lady asked the father how many tickets he wanted. He proudly answered, “I want eight children's tickets and two adults' tickets, so I can take my family to the circus.”

    The ticket lady said the price. The man's wife lowered her head and there was no smile on the man's face. He quietly asked, “How much did you say?”

The ticket lady said the price again. The man didn't have enough money. How could he tell his eight kids the bad news? My dad put his hand into his pocket and pulled out a $20 bill and dropped it on the ground．(In fact, we were not rich!) Then my dad said, “Excuse me, sir, this dropped out of your pocket.”

The man knew what was going on. He looked into my dad's eyes, held my dad's hand in his, and took the $20 bill. “Thank you, sir, thank you. This really means a lot to me and my family.”

    My father and I went back home. We didn't go to see the circus that night, but we didn't care.

    "It's time to wake up, Emily," my mom sings from the kitchen. I pretended to open my eyes. Why didn't the alarm on my cell phone ring?

    Soon, I realized it was April 8, the day for my program: "A day without technology." I didn't realize what I had gotten myself into until I was driving to school in my car. No radio blasting my favorite songs. I had to sing to myself.

    As soon as I got to school, I went to the library to print out my English project from my flash drive. "Uh-oh," I thought. "This isn't expected." Finally, I had to spend nearly an hour writing the report again.

    The school day went on and I finally got used to the rules. This wasn't so hard! I could do this every day.

    I drove home in silence again, and my mind eventually went into after-school mode (模式), depending on what I would eat for supper and who would be voted off (被淘汰出局)American Idol later that night. The last thing I knew, I was chat with friends on Face book, check email and watch a video on YouTube, all at the same time!

    My mom walked in and her jaw dropped.

    "What happened to no homework?" she asked me. I froze for the second time that day and ordered myself to go back to reality. I had failed.

    This experiment, which many teenagers would never have the courage to try, was actually convenient to me. Even though my attempt(尝试) at going about my day without these luxuries (奢侈品) was a failure, I realized that if I really tried, I would be completely successful without my addiction to technology.

    These devices suddenly make my life easier, and I'm sure I wouldn't practice getting rid of them altogether, but I do believe the lives of today's teenagers would be dramatically different without our tech dependence.
