It is easier to float in the ocean than it is to float in a swimming pool. Do you know why?
Ocean water is full of salt— and salt water can hold up more weigh than fresh water. See for yourself!
You Will Need:
● 3 cups of warm water
● Measuring cup (量杯)
● Wide-mouthed jar
● Salt
● Spoon
● Raw (生的)potato
You Will Do:
1. Pour 1.5 cups of warm water into the jar.
2. Add 1/3 cup of salt.
3. Stir(搅拌) until the salt is completely dissolved.
4. Add another 1.5 cups of water. Pour it slowly over the back of the spoon into the jar so that the two liquid will not mix together.
5. Gently place the potato into the jar. Do not drop it.
What Will Happen:
The potato will sink— but only halfway!
Why?
Salt water is heavier than fresh water, so it will stay on the bottom. The fresh water will remain on top.
The potato is heavier than the fresh water, but it is lighter than the salt water. That is why the potato will sink halfway down.
36. In the experiment, what should you do right after you pour the water over the spoon?
A. Add the salt to the water.               B. Stir the salt into the water.
C. Place the potato in the jar.              D. Pour warm water into thejar.

Kataria is the founder of the worldwide laughter movement. The celebration of world Laughter Day is a positive activity for world peace and is intended to build up a global sense of brotherhood and friendship through laughter. The first “World Laughter Day” gathering took place in Mumbai, India, on 11th January 1998. 12,000 members from India and international Laughter Clubs attended it. Now there are over 5,000 Laughter Clubs worldwide on all 5 continents.
    “HAPPY-DEMIC” was the first World Laughter Day gathering outside India. It took place on 9th January 2000. In Copenhagen, Denmark , more than 10,000 people gathered at Town Hall Square. The event went into Guinness Book of World records. “World Laughter Day” is now organized on the first Sunday of May every year. Hundreds of people gather worldwide on that day to laugh together.
    Today, many people fear widespread international terrorism（恐怖主义）. The world has never faced so much unrest before. People are at war within themselves. Laughter is a universal language, which has the ability to unite humanity without religion（宗教）. Laughter can build a common connection between various religions and create a new world order. The idea may sound over-ambitious (野心太大的), and maybe it is. But maybe it is not. It is our deep belief that laughter and only laughter can unite the world, building up a global sense of brotherhood and friendship.
