Charting the Great Waterfall

I set sail along the slick kitchen counter until the white plain dropped straight down into a colossal metallic canyon! It was the sink basin, glistening like a sunken cavern. Right at the cliff's edge, a green scrub sponge was perched like a friendly mossy reef. I steered my ship close, raised my fist, and reached out to tap it. When my knuckle pressed down, a single giant water droplet bubbled up from the pores and rolled right past my hull! A perfect freshwater spring for any hungry crew! Hahaha!
