The Obol's unique design doesn't just throw up a wall in the center like most dual-compartment bowls in the market. Instead, the spiral and sloping shape creates a pathway on one corner, where you can let some of the cereal slide (either by tilting the bowl carefully or pushing it with a spoon) to join the milk on the other side.
The bowl's base is actually shaped like a handle, too, in case you'd rather keep your hand far away from the food.
