Show a reactivity series (K > Na > Ca > Mg > Al > Zn > Fe > Pb > H > Cu > Ag > Au, top to bottom = most to least reactive). The child can drag any metal from the series into a beaker containing a salt solution of another metal. If the metal is MORE reactive than the metal in the solution → REACTION!
