science fair time- Rubens Tube! Answered

Well, it is science fair time once again and me and my friend have decided to build a rubens tube and test differences between frequencies. Anyways, There are 2 good instructables on the subject and i am not sure which one to pick. We need to start building it this weekend so all the parts must come from home depot or somewhere. any suggestions?

Both are good - when I (eventually) get round to building mine, I probably won't follow either exactly, but cherry-pick from both 'ibles and the ideas presented in the comments. Why don't you do the same, then publish your own Instructable on how you turned them into a Science Fair project, and maybe what your teachers said about the work?

They're really similar. Either one will work ;-)
