You Too Can Walk on Water你也可以走在水

February 28th, 2007 · by David Bradley 2007年2月28日,大卫布拉德利

Everyone has seen this video by now haven’t they?大家都看到了这部影片现在已不是吗? Well, I hadn’t until very recently and because it’s got a science type theme I just had to share it.那么,我没有,直到最近,因为它有一个科学型的主题我只是分享。 Thixotropic materials make walking on “water” quite possible, but don’t stand still for too long.触变材料,使走在“水”很可能,但不要原地踏步太久。

The pool is actually filled with a solution of cornstarch (cornflour in the UK) and behaves very much like a liquid when you try to stir or disturb it slowly, but apply a force more quickly (such as running across a big tub of it) and it behaves more like a solid.泳池,其实是充满了解决玉米淀粉( cornflour ,在英国)和表现十分相似的液体,当您尝试要挑起或扰乱它缓慢,但申请的力量,更迅速地(如运行的全国一个大浴缸,资讯科技)它的表现更象了坚实的。 Such这种 thixotropic触变 , or non-newtonian fluid behavior is essentially down to the way the molecules comprising the mixture can move relative to each other. ,或非牛顿流体的行为,基本上是下降到方式分子组成的混合物可以提出相对对方。

There’sa nice experiment you can do at home有很好的实验,你可以做在家里 here这里 , unless you’ve got a tub as big as the one the “experimenters” in the video used! ,除非你建立了自己的浴缸那么大一个“ experimenters ”在录像带中使用!
