Hua hospital.
In the laboratory of the color-changing materials Research team, a handkerchief-sized piece of cloth was already placed in front of yang duanhe.
Half of the cloth was placed on the stainless steel experiment table, and the other half was suspended in the air.
One could see that half of them had turned white under the illumination of the incandescent lamp, while the other half, which was attached to the stainless steel, had completely turned the silver-white of the stainless steel.
Just this effect alone had far exceeded the several levels of research he had done before.
"let's go outside and find a place to try it out." yang duanhe said directly. he picked up the cloth and led his men out of the research room to the courtyard where their group was allocated.
They arrived at the courtyard.
yang duanhe placed the cloth under the shadow of a tree. in an instant, the cloth changed color to the same color as the shadow.
