A falling stream generates outward flow without piling up. Watch your faucet run into a partially full sink: there’s a small depression where the stream impacts it — while the pressurized region under the stream pushes the water out and away. This is in contrast to honey, which will form a mound when a stream hits, because of its higher viscosity.
