When we put a penny in a flask containing nitric acid a chemical reaction happens, liberating nitrogen dioxide as a gas.
"Warning: Do not attempt this reaction. The gases produced are dangerous and must be properly controlled and ventilated. Also, the concentrated nitric acid used can cause severe acid burns.
If you've been keeping up, you know that we already popped a small balloon, but our intention all along was to go big. After purchasing larger balloons, we did a test run... and it was still essentially a flop. In this experiment, we use a snazzy apparatus with dual layered balloons to combat the corrosive nature of the Nitrogen Dioxide gas (and it really is corrosive).
The liquid in the first flask is concentrated Nitric Acid. When we placed a number of pennies in the flask, the acid reacted with the copper and released the nitrogen dioxide. The blue color in the copper solution is due to the copper ions.
You will notice a sort of double pop, and that is due to our double balloon layer. Contrary to popular belief, it is not magic.
If you're observant, you will also notice just how corroded the popped balloons did get. And, if you can take your eyes away from the balloons and smoke, check out the blue acid solution boiling in the foreground.
The overall after hours reaction should be considered a success, and hopefully you will find our diligent and persistent work to be enjoyable :)"
