Hear OK and self-restrained " fountain " , still be color, true? I should try today!
听说可以自制“喷泉”，还是彩色的，真的吗？今天我要来试一试！
To do this interesting test, I prepared a few kinds of a packet of a bottle of a tube, white vinegar, saleratus, common color designedly an a bottle of pigment, essence that wash clean, ladle and a few water.
为了做这项有趣的实验，我特意准备了一支试管、一瓶白醋、一包小苏打、常见的几种颜色色素、一瓶洗洁精、一个勺子和一些水。
Interesting experiment begins! I take one spoon soda to be put into test tube with ladle above all, wash clean essence into 3 to the drop in test tube then, drip the pigment of gules, green, blue, yellow into test tube respectively next, will white finally vinegar also falls into test tube, right now the liquid in test tube arrives probably the half of test tube. My screen lives breath, the hour that witnesses a miracle arrived, like seeing it is boiling that the liquid like bubble resembles only, go out from the spew in test tube, speed does not calculate very fast, but the appearance of multicoloured makes me very surprizing, be too good-looking really!
有趣的实验开始啦！我首先用勺子取一勺苏打放入试管中，接着向试管中滴入三滴洗洁精，然后把红色、绿色、蓝色、黄色的色素分别滴入试管中，最后将白醋也倒入试管中，此时试管中的液体大概到试管的一半。我屏住呼吸，见证奇迹的时刻到了，只见泡沫般的液体像是沸腾一样，从试管中喷涌而出，速度不算很快，但是五颜六色的样子令我很惊喜，真是太好看啦！
Nevertheless, why to meet such?
不过，为什么会这样呢？
I get online examined a data, because many carbon dioxide gas is made when sodium bicarbonate and white vinegar reaction,be so, the carbon dioxide in test tube accumulates more more, the essence that wash clean offerred a large number of bubble, go out from spew of test tube coping as bubble after be full of test tube. As a result of the apply colours to a drawing of pigment, because this forms the peculiar phenomenon of fountain.
我上网查了资料，原来是因为小苏打与白醋反应时生成大量的二氧化碳气体，试管中的二氧化碳越积越多，洗洁精提供了大量泡沫，当充满试管后便随着泡沫从试管顶部喷涌而出。由于色素的渲染，因此形成喷泉的奇特现象。
This can be too magical really! I give a name to it for " chromatic fountain " . Classmates, in small experiment accumulate containing interesting scientific knowledge, if you also like this experiment, might as well also try in the home.
这可真是太神奇了！我给它起名为“彩色喷泉”。同学们，小小的实验中蕴含着有趣的科学知识，如果你也喜欢这个实验，不妨在家也试试。
