This Donut with Sprinkles Model of the Universe is very similar to a well-known way of explaining the expanding universe. Called the Raisin Bread Model of the Universe, the universe is like a loaf of rising bread. As the loaf rises (as the universe expands), raisins (galaxies) within it are all getting farther apart from each other.
