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(攪拌) 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.

This is a true story of how my car got stuck in water and how a stranger helped me during the worst rain storm.

Last Sunday, the sky was grey when I woke up. The weather report said rain was coming, but I couldn’t stay home just because of rain.

Around 8:00 am I had a doctor’s appointment. It wasn’t raining then. At 9:00 I left the doctor’s office to drive to work, and it was raining hard. I just had to go about 5-6 miles down one main road to get to a nearby school, where I could stay until the rain ended. Unfortunately, the road in front of the school was flooded, and my car stopped in the middle.

“Who is going to save me?” I wondered. I shut off the engine and turned on my flashers (車燈). I called 911. They were not helpful. I called my husband, even though he couldn’t come and help me.

My best decision of the day had been to wear rain boots. I took my umbrella and quickly got out and ran across the street to a shelter.

Before long, a tow truck(拖車) happened to pass by the street. The driver kindly offered to help me. At that moment, I really needed car pulled out quickly, so I trusted the stranger.
