Cloud names were hot recently, and cloudnine.com would definitely be valuable. I'm personally not a fan of names with useless words on the end of them (app, hub, inc, site, etc). How to make a paper gun is kind of long, but does have search volume for it. It would be best to build it out as a mini site. http://www.genericdomainfinder.com/domainvalue/HowToMakeAPaperGun.com
