River

Mnemonic

A massive storm unleashes torrential rain. You set out a soda can to catch a few drops, but within minutes the downpour fills every gully, merging into a roaring river that sweeps the soda can away like a tiny toy boat, tumbling through the rapids of a grand waterway.
Additional thoughts
Picture the storm clouds overhead, the little soda can overflowing instantly, and a wide, powerful river surging past—scale contrast makes it memorable. Left side is storm (water), right side is soda can.
Quick recall
A storm overfills a soda can, spawning a mighty river.
