What Makes an Ocean ‘Tide’ Come and Go?

Imagine the ocean is like a big balloon, and the Moon is like your favorite toy that pulls it. When the Moon gets close, it tugs on the water, making it rise, that’s high tide. When it moves away, the water goes back, that’s low tide. The Sun helps too! Sometimes they pull together, making really big tides, and sometimes they pull in opposite directions, making smaller ones.
