It’s way too easy to spot which merchandise is being advertised for girls in nearly every toy store. Packages are awash in a palate of pink and purple, and feature enough glitter to stun an elephant. Many of the playthings feature dolls and domestic scenes, while nearly all of the building blocks, science kits, and engineering sets are set up in the boys section. In a new video ad entitled “Princess Machine,” with with witty lyrics set to The Beastie Boys popular tune , “Girls,” toy company GoldieBlox shows us all how girls like to use their creativity and intelligence to play, and in this case to construct a fantastic machine! Quite simply, it rocks!
