  玉米淀粉俗名六谷粉。白色微带淡黄色的粉末。将玉米用0.3%亚硫酸浸渍后,通过破碎、过筛、沉淀、干燥、磨细等工序而制成。普通产品中含有少量脂肪和蛋白质等。
  Corn starch is commonly known as Six Grain Flour. White microstrip light yellow powder. Corn was impregnated with 0.3% sulfite, and then processed by crushing, sieving, precipitation, drying and grinding. Common products contain a small amount of fat and protein.
  玉米淀粉的特殊特性: 玉米淀粉加水有种奇怪特性:受快速撞击会变硬,受慢速撞击反而不会。将玉米淀粉和水以约3:2之重量比混合搅拌均匀,视情形增减水量,这种名为“欧不裂”oobleck的剪切增稠流体,是一种非牛顿流体.
  Special characteristics of corn starch: corn starch with water has a strange characteristic: it will harden by rapid impact, but not by slow impact. Mixing corn starch and water at a weight ratio of about 3:2 and mixing evenly, the shear thickening fluid called "Euclidean splitting" oobleck is a non-Newtonian fluid.
  1.倒出此制成品约5mL之量于手掌,双手搓揉即可将原先液态之制程品搓成丸子状之固态小球,停止搓揉后约半秒后该小球将迅速"融化"而回到液态,可重复搓揉动作演示此种特殊性质。
  1. Pour out about 5mL of the finished product on the palm, and rub it with both hands to make the original liquid product into a ball-like solid ball. After stopping rubbing for about half a second, the ball will quickly "melt" and return to the liquid state. This special property can be demonstrated by repeated rubbing.
  2.将约50~100mL之制成品放于免洗纸杯内,使用免洗纸杯或塑胶杯是为了轻量化方便操作,先轻轻倾斜纸杯给参与者观看纸杯内部液态的制成品,接着快速将纸杯内制成品对观众作泼洒动作,这种现象可以令参与者印象深刻。
  2. Place about 50-100mL of finished products in the wash-free paper cup. Use the wash-free paper cup or plastic cup for lightweight and easy operation. First, gently tilt the paper cup to show the participants the liquid products inside the cup. Then quickly sprinkle the finished products inside the cup to the audience. This phenomenon can make participants impressed.
  3.将约50~100mL之制成品放于免洗纸杯内,先轻轻倾斜纸杯给参与者观看纸杯内部液态的制成品,然后颠倒免洗杯但快速上下摇晃行走一段距离后将杯子回正,此时因为非牛顿流体产生力量对抗快速之剪应变化,因此杯中之制成品并不会泼出。
  3. Place the finished product of about 50-100mL in the wash-free paper cup, gently tilt the cup to show participants the finished product of liquid inside the cup, then reverse the wash-free cup, but swing it up and down quickly for a distance, and then return the cup. At this time, because the non-Newtonian fluid has the power to resist the rapid shear strain, the finished product in the cup will not spill out.

  4.将数升之制成品放于大型浅盆内,参与者可以快速跑过浅盆中的制成品而不下沉,若行走速度较慢则会下陷于制成品中.5.将50~100mL之制成品放于朝上之音响喇叭震动膜上,开启一定音量之低频声波振动及可观察制程品的扭曲成型变化
  4. Place several liters of finished products in a large shallow basin. Participants can quickly run through the finished products in the shallow basin without sinking. If they walk slowly, they will sink into the finished products. 5. Place 50-100mL finished products on the upward sound horn vibration film, open a certain volume of low-frequency sound wave vibration and observe the distortion of the processed products.
