Mnemonic

A violent storm rips a waste bag right out of someone's hands, launching it into the nearby stream. The current seizes it instantly, dragging the waste bag downstream, spinning and tumbling through the rushing water until it vanishes around the bend.
Additional thoughts
Picture the sequence top-to-bottom: storm overhead, waste bag caught mid-air, stream below pulling everything along. The current is the unifying force that carries debris away.
Quick recall
A storm hurls a waste bag into a stream, where the current sweeps it away.
