We’re rolling out our picks for this year’s Holiday Gift Guide, which focuses on STEM-inspired goodies.

Business: Cracked Candy
Product: Tooth-friendly candies
Price: $4.99

When Cracked Candy founder Flora Pringle — once a British science teacher — moved to the United States for her husband’s job, she initially felt lost. Unable to find the part-time position she sought as a young mother, Pringle had time on her hands. “I came across xylitol on a tube of toothpaste and was intrigued, so I looked it up. It looks and tastes like sugar, but is good for your teeth and safe for diabetics,” she says. Pringle perfected the candy through experiments during her child’s naps. Today, Pringle says the business “has allowed me to combine my skills and passions: science, food, health and family.”

Editor’s Note: Our judges were pleasantly surprised to discover that the candy itself is broken into pieces reminiscent of crystals. They are, as one judge noted, “unique, like snowflakes.” The lemon and orange varieties were especially popular, but all four are refreshing, and come with a cooling sensation for the taster.
