Dissolving a pure gold bar in acid
What I have here is 100g of pure gold, and at around $57 US per gram, it's worth about $5700. It's one of the most expensive, and precious things that I own, but I think I'm just gonna destroy it using acid.
WARNING: Aqua Regia is an extremely corrosive mixture of nitric acid and hydrochloric acid. It was handled in a controlled environment and it's very dangerous if used improperly.
