This 4 inches (10cm) in diameter squishy Earth's core model half-dome is great for demonstrating geology in the classroom and as a super-satisfying squeezable stress reliever. It features a North and South America map on the surface and elements of the core on the cross-section (crust, mantle, outer core, inner core.)
