小实验

I dropped the water again, only put baking soda, and lit a match on top, but the fire didn't go out. I dropped the baking soda again. I put the white vinegar on it. I lit a match and put it on the top. The fire didn't go out. Now I know that baking soda and white vinegar mix together to put out the fire.

我想再试一试，先把小苏打粉倒进小碗里，再倒进白醋。碗里发出“嗤嗤”的声音激烈地冒出雪白的泡泡，像水煮开了一样；难闻气味一下来了。我又划了一根火柴，慢慢接近水面，离水面一厘米的地方火又灭了。

I'd like to try again. First, pour baking soda into a small bowl, then white vinegar. The sound of "hiss and hiss" in the bowl fiercely produced white bubbles, like boiling water; the smell came down. I struck another match, slowly approaching the water, and the fire went out a centimeter from the water.

我追着问妈妈为什么？妈妈说：“上网查一下吧！”。在网上我看见是这样写的：小苏打和白醋混合后产生了一种新物质，这种物质是二氧化碳。二氧化碳可以使燃烧着的火熄灭。

I ran after my mother and asked why? Mom said, "check it online!". On the Internet, I read this: baking soda mixed with white vinegar produces a new substance, which is carbon dioxide. Carbon dioxide can extinguish a burning fire.
