=== EXPERIMENT ===

To examine the essence of concrete, I visited a Bio Lab and observed concrete under a microscope. Inside, I found countless small stones, and around them, even traces of moss were growing, making it appear as if a small world existed within. Through this process, I became increasingly interested in these small stones. It led me to wonder whether these tiny elements might actually be what supports the concrete itself. In fact, concrete is made by mixing water, cement, and aggregates such as gravel and sand. These small stones, in particular, are essential for giving concrete its strength and durability, preventing it from easily breaking apart. Although they are too small to be clearly recognized without a microscope, the presence of these countless tiny stones ultimately makes the existence of concrete possible.
