More time and more acceptable answers (mountain dew, 7up etc.). A lot of them I've never even seen, so maybe some more popular brands? Also, you missed some pretty big ones, like tango...
Agree, need way more time, and I also tried Mountain Dew and 7 Up without luck. Also agree that RC or Royal Crown Cola is missing. (Can't wash down a Moon Pie without an RC.)
7 up
7-up
should all be acceptable
Mountain Dew doesn't work, but mt. dew does?
