研究人员称，有一种新材料也许能提供一种可以让物体隐形的思路，因为这种材料可以改变光线和其它形状的辐射线在物体上的折射方向。
New materials that can change the way light and other forms of radiation bend around an object may provide a way to make objects invisible, researchers said.
我利用不同颜色的光照射晶体，冰晶结构就像复杂的棱镜一样将光线折射到不同的方向。
I use different types of colored lights shining through the crystals, so the ice structures act like complex lenses to refract the light in different ways.
例如，古人观察到了水滴和某些雕琢过的宝石可以把光按照一定的方向折射出去。
For example, ancient people discovered that drops of water and certain gemstones distorted light in a predictable way.
