I'm not vaporizing urine rather a chemical compound of Nickel. It's an extraction process of nickel. The experiment was very simple but took a long time to get the precipitate form of Nickel sulfate. I completed two experiments together today. Went out from home to varsity early in the morning without taking breakfast, because I didn't have much time for it. Due to hungriness, I become so weak at the last moment. So tired now, after taking my lunch. Want to take a short nap! Zzzz!
