Caustic Soda Down Drain Access

A fine, invisible mist filled the crawlspace beneath the kitchen, settling on the wooden joists, the fiberglass insulation, the cardboard boxes of Christmas ornaments. Clara, upstairs, heard only a faint hiss, which she mistook for the sound of success. She rinsed the sink with water, as instructed, and went to bed.

Clara bought the yellow bottle from the hardware store, its cap sealed with a childproof lock and a skull-and-crossbones warning. That night, she read the instructions three times. She put on Tom’s old gloves, too large for her hands, and his goggles, which fogged immediately. She poured half the bottle down the kitchen drain—a thick, syrupy liquid that smelled of nothing but anticipation.

At first, nothing happened. Then the drain burped. A thin wisp of steam curled up from the sink, carrying a chemical bite that made her nose hairs curl. The sound that followed was not the gurgle of relief she expected. It was a low, deep crack , like ice breaking on a frozen lake, followed by a wet, tearing noise.

Her foot plunged through up to her ankle. She yanked it back, skinning her shin. The hole she’d made wept a thin, milky fluid that sizzled against the remaining linoleum. She looked down into the darkness and saw her basement ceiling glistening, wet and necrotic, like the inside of a gangrenous wound.

“Ma’am,” Del said, his voice hollow, “what did you pour down there?”

Clara stared at the hole in her kitchen floor. The house’s heartbeat had gone silent. In its place was a slow, wet dripping sound—the sound of everything she had built being turned into soap.
