Classmates, do you like to do scientific little test? I did today interesting small experiment, be called the hubble-bubble of bounce.

同学们,你们喜欢做科学小实验吗?今天我就做了一个有趣儿的小实验,叫做弹跳的泡泡。

The data that needs preparation has water, the essence that wash clean, sizy, straw, glove. The young associate that I called up myself people do solid composition together with me check. I and my young associate people the dispute arises, some saying that can play start to come, some saying that cannot play start to come, gabble ground argues.

需要准备的材料有水,洗洁精、胶水儿,吸管,手套儿。我叫来了自己的小伙伴们和我一起做实验。我和我的小伙伴们争论起来,有的说能弹跳起来,有的说不能弹跳起来,七嘴八舌地争论。

The experiment began, we mix water the essence that wash clean according to 3: The scale of 1 mixes together, rejoin a few glue. After been do, I wear a glove, ground of too impatient to wait blew bubbly bubble with straw. Put on the back of hand, but the result is a little disappointed, what add because of water is a little much. Failed so. I was done again, succeeded this eventually. Hubble-bubble rises in the bounce on the back of hand. I and young associate people happy happy to dance.

实验开始了,我们把水和洗洁精按照3:1的比例混合在一起,再加入了一些胶水儿。做好之后,我就戴上手套,迫不及待地用吸管吹了起泡泡。放在手背上,可是结果有点儿失望,因为水加的有点儿多。所以失败了。我又做了一次,这次终于成功了。泡泡在手背上弹跳起来。我和小伙伴们开心地手舞足蹈。

The experiment is decoded, the hubble-bubble after moisture evaporates explodes easily, after adding glue, hubble-bubble moisture evaporates not easily, defeat not easily. In addition, because there are a lot of fine furs on the glove, sex sticking Fu is stronger, flexibility is very enough, then hubble-bubble can be on our the back of hand bounce.

实验解密,水分蒸发后的泡泡易爆,加入胶水后,泡泡水分不易蒸发,不易破。此外,由于手套上有很多细毛,粘覆性比较强,弹性很足,于是泡泡就能在我们的手背上弹跳了。

Scientific test but really interesting ah! It also grew me a lot of knowledge.

科学实验可真有趣儿呀!它也增长了我很多知识。(文/宋昕蔚)
