Place about 5 grams of zinc dust in an evaporating dish. And enough NaOH solution to cover the zinc and fill the dish about onethird. Place the dish over a burner, or hot plate until the solution is near boiling. Prepare a copper penny by cleaning it thoroughly with a light abrasive (Brillo pads work well).
