An "Invisibility Cloak" is a fictional garment that renders the wearer invisible to the naked eye. Popularized by the Harry Potter series, it is often depicted as a magical item that allows characters to move unseen. In real-world science, researchers are exploring materials and technologies, such as metamaterials, that could bend light around an object, creating a similar effect. The concept of invisibility has fascinated people for centuries, appearing in various myths and stories. While true invisibility remains unattainable, advancements in optics and cloaking technology continue to inspire innovations in fields like military applications and stealth technology.
