One could be the lighting of a firefly, because there is a chemical reaction that happens inside of the firefly that makes it glow, and another could be making food, because you have to add baking soda in some foods, and it reacts with other ingredients. Hope that helps.
I'm confused on your question. Were 8 men randomly selected. Or 8 men randomly selected from "Football Fantasy XIV". In that case it would be all of them. But using 8 men*.65= 5.2. So it's gotta be 5 outta 8 men who think they be all knowing in fantasy football. I'm sorry lol I was confused I hoped I helped. Have a good day.
