Everyone has seen this video by now haven’t they?大家都看到了這部影片現在已不是嗎? Well, I hadn’t until very recently and because it’s got a science type theme I just had to share it.那麼,我沒有,直到最近,因為它有一個科學型的主題我只是分享。 Thixotropic materials make walking on “water” quite possible, but don’t stand still for too long.觸變材料,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,其實是充滿了解決玉米澱粉( cornflour ,在英國)和表現十分相似的液體,當您嘗試要挑起或擾亂它緩慢,但申請的力量,更迅速地(如運行的全國一個大浴缸,資訊科技)它的表現更象了堅實的。 Such這種 thixotropic觸變 , or non-newtonian fluid behavior is essentially down to the way the molecules comprising the mixture can move relative to each other. ,或非牛頓流體的行為,基本上是下降到方式分子組成的混合物可以提出相對對方。
There’sa nice experiment you can do at home有很好的實驗,你可以做在家裡 here這裡 , 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麼大一個“ experimenters ”在錄像帶中使用!

Very cool.非常酷。

Good thing Yeshua didn’t need the cornstarch…一件好事,耶穌並不需要玉米澱粉…
