Don't call it a lollipop: This hard candy is screwed onto the base of the toy, which chortles when it's shaken. The design challenge here involved getting the components in the toy to work while keeping it small enough to fit comfortably on a retail counter. A light-up airplane fan candy--complete with a motor and a battery-powered fan--is CandyRific's bestseller. Number of units sold in 2006: 10 million (including all versions of the toy). Price: $2.99 retail for most versions.
