person A: I felt like I was on the top of the world when I won the science fair in middle school. No better feeling than that for a small child. 
person B: Congrats! That would be really exciting. What was your project?
person A: My project was to show what farm poop produced the most gas when it decomposed. I put the poop in a bottle with a balloon on top. Whatever balloon grew the largest_comma_ was the one that released the most gas.
person B: That's a very interesting topic. I would have loved to have seen that!
