Bloomed and Unbloomed

My husband gave me this: a chocolate bar that had melted and cooled in the car. (He knew I'd love it.) Most of the surface bloomed, but patches stayed dark and shiny. Were these sections protected by the wrapper? Did they fail to melt? Or was there something else going on?

Candy Experiments news

Great news! There's a Candy Experiments book giveaway at, so head on over if you don't have a copy already.

On another note, Candy Experiments 2 just got listed on Amazon, due to be released in December. I can't wait to see it!


I did something unusual with the leftover Halloween candy tonight--fed some to a child. We were making s'mores and needed ingredients, so the sugar-free Peeps Valentine heart went on top of the Hershey Almond bar. The verdict? The chocolate melted first, marshmallow got a little bit melted, and the whole thing was devoured.


The USA Science and Engineering Festival was a spectacular success! We taught our experiments, including Sink a Marshmallow, Acid Test, and Find Hidden Candy, to thousands of kids and their parents. I also did an author presentation, an author signing, and an interview on Sirius radio, so we've reached even more people to tell them that candy experiments are both fun and educational.

We had great helpers, including my sister (teaching Find Hidden Candy), homeschool families, and my own family. My kids made great candy experiments teachers.
