Roller Coasters--help a writer out? I'm a freelance writer working on an article about how roller coasters work. It's to be a fairly short article for a children's Web site, so I don't need massive amounts of information (and I am doing research of my own as well), but I thought it might be fun get some tips from someone here. Would anyone like to explain to me in your own words how a roller coaster works, or give me a link to a great explanation? Also, if you want to give me any ideas on what would make this easier and more fun for a kid to learn about that would be great too. I will not plagiarise your wording. I am very careful about that. I only want some input. Thanks!
