Replacing candy thermometer with meat thermometer?
I have a candy recipe I really wanna try tonight but I only have a meat thermometer. Can I use that instead of a candy thermometer? Or is there some other way to tell when the candy is at the "hard crack stage, or 300 degrees on a candy thermometer"?

Or for those who are so inclined, you can easily make your own soda machine http://www.popsci.com/diy/article/2012-06/how-make-your-own-home-carbonation-system
