每日口說挑戰為什麼牛奶上的穀片匯聚在一起？（The Cheerios Effect）

Intro:
Hi, VoiceTubers. This is Tera. Very pleased to see you here, and today, we are going to take a look at some awesome science in everyday life which you might not have noticed before. Most of us have experienced having cereal for meals, right? But, have you ever wondered why the cereal sticks together in the middle of the edges of the bowl? Without further chit-chat, please allow me to introduce today’s video to you. You’ll discover lots of cool physics that you will definitely find interesting in it. All right, today’s featured sentence is…

Featured sentence: The chemical properties of soap lower the surface tension of water, so anything relying on surface tension to stay afloat will sink.

Tips:
chemical: three syllables with the stress on the first one. "ch" in "che" is a /k/ sound, so it is pronounced as /kɛ/. The vowel in "mi" is a short /ɪ/, "mi", and "c" in "cal" also has a /k/ sound, which makes this syllable become /k!/. "che-mi-cal".
properties: three syllables with the stress on the first one as well. Firstly, "pro" is an opened /prɑ/ sound. Secondly, the onset of this syllable "per" will have a little "b" sound but not so much. And then, the single form of this word is "property", but since we get a plural here, this word is "pro-per-ties".
surface: two syllables with the stress on the first one. "Sur" is the same as "sir". What we should pay attention to is its second syllable, which is "face" /fɪs/ but NOT "face". Altogether, "sur-face".
tension: two syllables with the stress on the first one as well. "ten" is just like how we say the number "ten" but with a higher pitch because there’s a stress on it. "sion" is the same as "tion". Again, "ten-sion".

Vocab:

Outro:
How do you feel after watching this video? I was like, "wow", all the time when I was watching it. It’s especially inspiring to know that we can actually observe lots and lots of exciting phenomena, either a chemical one or a physical one, in life, and if you wish, there are also many simple science experiments you can conduct by yourself at home. For example, you’ll be able to create a small volcano in only two steps. First of all, combine the vinegar, water, dish soap, and two drops of food coloring into the empty soda bottle. Second, Use a spoon to mix the baking soda slurry until it is all a liquid. Then, time for the eruption. Pour the baking soda slurry into the soda bottle quickly and step back! Real quick, real easy. So, if observing cereal with the milk in your bowl makes you feel bored and you’d like a more thrilling experience regarding science, here is one for you. Stay safe and stay healthy. It’s Tera from VoiceTube, I’ll see you in the next episode.

[2:43] The chemical properties of soap lower the surface tension of water, so anything relying on surface tension to stay afloat will sink. 肥皂的化學特性減低了水的表面張力，所以任何依賴表面張力漂浮的物品都會下沉。

#我的cereal是不會有機會薄薄一層汪洋中小筏的，肯定是一座小山丘XD
#吃掉就對了，不要再觀察了！
This interaction holds the Cheerios at the surface of the liquid, like little toasty rafts drifting together on top of a sea of cereal milk.

☺The chemical properties of soap lower the surface tension of water, so anything relying on surface tension to stay afloat will sink.
肥皂的化學特性會降低水的表面張力，讓任何依靠表面張力飄在水面的東西往下沉。
【心得】不論是Oreo或Cereal或麵包，我都比較偏好乾吃，我不喜歡浸在牛奶或湯裡，那種糊糊的口感。
