When some seemingly unnecessary items appear in life, how their combination will make the light project change. Does the refraction of light change when the back of the jar is cut into different shapes. When a prism spreads light, what will the light we see again look like? In dark space, light and shadow make up the universe. Is the endless universe pitch black? This design creates an aurora-like lighting effect through the exploration of lighting, showing different lighting effects under different lighting colors. In this design, a beam of light is dispersed around a prism through a broken can, creating a different kind of beautiful light and shadow effect. At the same time, through the product itself, it reminds people that every seemingly inconspicuous item in life should be tried again, just like a soda can. We should not throw it away after drinking it. Instead, explore the infinite possibilities of each product. We should be curious, enthusiastic, and constantly exploring the world.
