Nice “picture story!”

Today, we’re going to show you how we recovered the gold from old motherboards using do-it-yourself methods. Please note: The chemicals used in this demonstration are extremely dangerous, especially in the concentrations used. Therefore, we strongly discourage you from attempting to reproduce this experiment at home.
