<p>Let's say you made up a crazy idea for an essay (case in point: JHU's 10$ essay) and you said that you were going to go rafting on a raft you made with water bottles. (Yes, it's possible) Do you think I should include the calculations to back that up? (e.g. each water bottle has an approximate buoyant force of 250g, and so to support a person weighing 100 pounds, it would take blabla # of bottles) Or do you think its just the idea that counts and that the ideas don't actually have to be real-life workable?</p>
<p>Thanks.</p>
