What Household Items Can I Use To Make A 3D Atom Model Of Lithium?

I had to make one for an assignment and I used; polystyrene balls covered in aluminium foil for the nucleus and electrons, wire rounded into circles for the outermost shells. Just stab the polystyrene balls onto the wires; 2 on the inside and 1 on the outside. Hope it helps ! (;
