Cola storm

One day during the summer vacation, when I took out a cola from the freezer and was preparing to drink, I suddenly thought: This is too cool for Coke, others are doing "Coke Ice", I am now doing "hot cola" to see what it tastes like? If it is good, then I am the inventor of "hot cola", and I would like to ask my teachers and classmates to taste a bite!

So I took out a pot. Fill the inside with boiling water. Then, put the cola into the basin. After about 5 minutes, I thought: "It's cooked"! So, take the cola out. The finger just touched the can of the can, only heard a "click" sound. I saw the white walls, and turned into a red and yellow dotted flower wall. The beautiful furniture turned into an "athlete" with "sweat"! And me? It was also poured into a "falling chicken".

I think: bad! I have to eat my mother's "simmered meat" tonight. I quickly took a towel and took the chalk to the wall! But it doesn't work, the more it gets dirty, the more it gets darker. At this time, my mother opened the door and came back. I whispered my mother with a timid look: "Mom, I made a mistake..." Mom began to look very ugly, but after listening to me, not only did she not criticize me, but instead Smiled and told me the mystery of this. It turns out that there is carbon dioxide in the Coke canister, which is inflated and contracted. Therefore, the cola expands when it encounters heat, and it will explode when it reaches the extreme.

The language of the article is fluent and vivid. For example: "Beautiful furniture turned into an 'athlete' with a sweat-filled face! I? It was also poured into a 'falling chicken'," and "simmered meat" . In addition, the scientific principles are also explained in the work.
