Baking soda is one of those things that just seems to have a never-ending amount of uses. From cooking and cleaning to science experiments and arts & crafts projects, there is a lot more you can do with it than you might originally think. Bust out a box of baking soda and see which direction inspiration pulls you for the Baking Soda Challenge!

Try for the obvious or attempt the obscure. Experiment with this multifunctional substance for a chance to win one of two iPad Mini 4s. There are too many uses to name for baking soda; now is the time to show off yours.
