An amusement park inside the living room? That’s what the Whurlybird is, in a nutshell. Safe, practical and speedy, this kid-powered whirling ride-of-fun seats two. Kids grab the handles and voila: 'round and 'round and 'round she goes, where she blows (chunks) nobody knows. “This thing is madness in a box,” explained retail buyer Guy Sanders, who saw it at the British Toy Fair. “It’s very portable, too — folding down and such.” The kids do the powering, so their excitement is in direct proportion to their stamina.
