AKA-Penny Operated Nitric Acid Fountain Nitric acid acts upon copper to yield nitric oxide in an exothermic reaction. The expanding gas displaces water from another flask; actually bubbles in this set up. When the gas cools, the water is drawn back into the flask, dissolving the nitric oxide and forming a blue solution with the copper ions still there. Very cool reaction.
