We're having a lot of fun with the post of my son's science project measuring the Phoenix urban heat island. The original post has nearly 60 comments and at least five long updates. Go back and read it all, its like a whole new post.
Commenters are slamming my son for having an R-squared that is insufficient (only 84%!) I have challenged them to post the R-squared of their vinegar and baking soda volcano they did in eighth grade.
