Electrolysis

HERE is the test for unbelievers
Who cannot see the electric beavers

Ferrying the metal flakes across
Anode and cathode with never a loss

Of one electron in the furious tides
Where worlds are joined and a world divides.

Copper and zinc, nickel and brass,
Gold and silver and iron pass

Through eyes of the atom and the beavers know
Precisely the place for each to go.
