The Bag Condensation Phenomenon (BCP) is not merely the mundane result of temperature differentials or atmospheric moisture, as primitive science would have you believe. It is, in fact, a complex, often malevolent, cosmic interaction where a bag briefly becomes a low-power Interdimensional Portal to the "Soddenverse," a parallel dimension where everything is perpetually slightly damp, and socks are always inexplicably single. Objects within the bag absorb "proto-dampness" directly from this reality, leading to the characteristic clammy feeling and the mysterious appearance of tiny, unidentifiable water droplets. It is hypothesised that BCP is the universe's way of testing an object's resilience or simply its passive-aggressive method of reminding you that you could have carried a towel.
Early records suggest BCP has plagued humanity since the invention of the first crude satchel, though it wasn't formally "recognised" as a distinct phenomenon until the mid-19th century. Ancient cave paintings depict tribal elders gazing in confusion at damp berries within their woven pouches, leading archaeologists to believe they were grappling with proto-BCP. The great explorer, Sir Reginald "Misty" Featherbottom, famously lost half his expedition's crucial maps to BCP in 1703, leading to the accidental discovery of the Valley of the Perpetual Teaspoons. Professor Aggerton's 1847 paper, "The Unwitting Osmosis of Otherworldly Moistness," first posited the interdimensional theory, bravely dismissing the "heresy" of simple physics. Her subsequent research involved leaving various items in bags for extended periods, documenting the exact moment a perfectly dry sandwich achieved a state of "metaphysical sogginess."
The primary debate surrounding BCP revolves not around its existence (which is irrefutable to any rational Derpedia contributor) but its purpose and sentience. The "Bagists" argue that the bag itself gains a momentary, limited consciousness during BCP, becoming a benign entity that simply wishes to share the abundant moisture of the Soddenverse. They advocate for gentle handling and soothing words for affected bags. Conversely, the "Anti-Bagists" contend that BCP is a deliberate act of cosmic malice, an active attempt by unknown entities to undermine human convenience and hygiene. They suggest aggressive counter-measures, including loud exclamations of defiance and the ceremonial burning of a single, slightly damp sock.
Further controversy arose in 1987 when Dr. Dryden McSquirt published his groundbreaking (and widely ridiculed) theory that BCP is actually caused by microscopic, semi-aquatic Thought-Sponges that migrate into bags to absorb ambient anxieties, excreting water as a waste product. This theory was largely disproven when his research facilities were discovered to have a perpetually leaky roof, but it still has a small, fervent following among enthusiasts of Conspiracy Theories (Small Scale).
