从网上偶然发现了很有趣的实验，作者的小外孙女用微波炉加热后的水与普通炉子加热后的水放凉后同时滋养修剪的植物和浇花，来比较这两种水的差异。图文并茂，还是很有说服力的。对我们认识微波炉的“危害”会有帮助。

Microwaved Water and Plants
Below is a science fair project that my granddaughter did for 2006. In itshe took filtered water and divided it into two parts. The first part sheheated to boiling in a pan on the stove, and the second part she heated toboiling in a microwave. Then after cooling she used the water to water twoidentical plants to see if there would be any difference in the growthbetween the normal boiled water and the water boiled in a microwave. Shewas thinking that the structure or energy of the water may be compromised bymicrowave. As it turned out, even she was amazed at the difference.Below are the pictures that were actually submitted with the project. Someof them were created with photoshop for the science fair presentation fromthe original photos, so the display would be consistant and easy to follow.The actual original photos are posted at the bottom with thumbnails. Theyare thumbnailed because the original photos were extremely high resolution.Marshall Dudley

Followup. We have seen a number of comments on this, such as what was thewater in the microwave boiled in. The thinking is that maybe some leachingtook place if it was in plastic. It was boiled in a plastic cup, so thiscould be a possibility. Also it was not a double blind experiment, so sheknew which was which when watering them. On top of that she was wanting themicrowaved ones to do poorly, and although most scientists would dismiss theidea, it is possible that her thoughts toward each plant had an effect aswell. Bottom line is, the results are interesting, and duplicate the resultsthat others have reported (try Googling '"microwaved water" plants') moreexperiments need to be done with better controls and as a double blindstudy. But this was a simple 6th grade science fair project, and was neverintended to be anything more than that.The plants were genetically identical, they were produced from graphs fromthe same parent plant, so that variable can be eliminated.
update 2:
Below are the original photos that were taken. The above photos were createdfrom them, some were simply shrunk and text added, but because ofinconsistancy in the original pictures, where some of them only showed oneplant at a time, or no picture was taken that day of the control, some ofthem are splices of the original pictures. So although some of the imagesmay appear to be faked, that was not the intention. The actual photos eachwere spliced from in in these below without modification.

微波有点恐怖:(

用电热壶烧水不知道有没有危害

微波烧水可能主要是因为改变了水分子结构，同样,热食物也会改变食物的分子结构。少用为好.

虽然现在也不常用微波炉煮食,但看来以后是尽量不用为妙了.

呵呵，我上次在这里看到微波炉的害处后已经以10块钱卖给收旧电器的人了，我们家阿姨可心痛了！

谢谢提供 其危害：一方面是加热改变食物分子结构，另一方面就是周围的辐射！

很有说服力，以后还是用加热的好

可悲啊！最怕不懂的人装懂！
微波炉对于西方人来说，类似于中国人的电饭煲，差不多每家每户都有，使用的历史比电饭煲还久，大家都知道鬼佬最怕死，如果微波炉真的有害健康，他们的政府早就下令回收了，何用我们中国人来担心？
要知道全球每年生产微波炉7000多万台，其中美国购买2000多万台，欧洲1000多万台，我们中国13亿人口才1000万台。
至于微波可以改变水分子结构，真是天大的笑话。建议先看一下物理书吧！
可以讲一个真实的故事，上次一个法国客户来我们实验室，担心微波有害。我们就把他带的NOKIA手机和一台微波炉做对比测试，结果NOKIA手机的微波泄漏大大超过微波炉。
这是很多人没有想到的吧！

不能否认的是这个实验结果很有趣，而且可重复。尽管原理是什么我们还不知道。这并不妨碍我们得出要慎用微波加热食物跟水的结论。
至于手机辐射的问题，很多人其实是想到了的，欧美很多实验室的长期研究也表明手机辐射跟某些癌症的相关性比大家之前认为的要高。
总之，我认为在不知道确切原理的情况下，慎用微波炉的结论是成立的。有机会我也重复重复这个实验看看。:)

别的方面我不懂， 微波炉还是知道一点的。

提醒一下， 做对比试验的时候双方都要在工作状态， 而不是待机状态。因为微波炉在待机状态下是不产生微波的，0微波。而手机在待机状态下是有微波产生的，在工作状态产生的微波更强。

测微波的仪器不那么容易找到吧。我是想试试看那个用微波炉加热过的水养植物的实验，看上去简单易行。原来那个实验使用塑料瓶加热的，我试试看用瓷碗或玻璃瓶会不会有区别。 youtube上也有人重复过这个实验，5天就能看到明显的区别，有机会可以在网上搜索一下。

楼主说的是 经微波加热的水

意在说明 同样是开水，电磁波加热和传统火加热，过程有别，结果也有别。

微波炉本身没有错，错在如何用得其所。

我现在一般把微波炉用于消毒食具。

真是有趣的实验。


都是方便付出的代价！

瓶子那个不看，只有最后的结果图，而且看上去，右边的也是有叶子萎的，口部那几片；但那个盆栽的就有问题了，左边植物明显有被剪枝的痕迹。如果是因为叶子萎了，那也要拍萎了的照片，拍什么剪掉后的？

如果怀疑有假，那不妨自己动手做个实验吧。

这个例子也许和"水知道答案"及其衍生系列有得一拼。

不知道宇宙之初氢氧结合化而为水时，其状况是否远胜于微波炉。

我忽然想到 氢原子最外层电子数是1 而氧原子最外层是6
这与天一生水地六成之是否有某种联系呢？
