If you've already followed Jennifer's advice about dealing with your Halloween haul and you still have candy leftover, perhaps it's time to donate that candy to science. Candy Experiments is a fabulous website full of fun, easy science experiments you can do with all sorts of leftover Halloween candy.
Did you know that you can detect the acidity of a candy by dissolving it in water and then adding baking soda? Watch what happens:

I'm eager to try these experiments, but there's only one hurdle. As my science-loving 5-year-old put it, "I'm way more interested in eating my candy than I am in science." Sigh.
(Found via Teach Mama, who actually got her kids to try it.)
