Here's another way to use up Halloween candy. Author Sharon Bowers has come up with lots of great crafts you can design with candy in her book Candy Construction: How to Build Race Cars, Castles, and Other Cool Stuff out of Store-Bought Candy.
Like me, Bowers has found that once she gets the kids excited about the candy project and turns them loose, they're not focused on eating it. She tells her kids no eating while building ("What construction worker snacks on the job?"), and lets them choose one piece of candy to set aside and eat after cleanup. Her final rule: "Candy construction workers always brush their teeth after work."
In my experience, letting the kids choose even one piece of candy to eat keeps them focused on eating, not testing, so my mantra is, "The candy is for experiments, it's not for eating." But it's nice to know that Bowers has also figured out ways to get children to play with candy instead of eating it. It really is possible to redirect kids' candy mania, and find alternative ways for them to enjoy their candy.
