Jell-O creates giggling youngsters using cookie cutters to design hand-held Jigglers. When that method isn't imaginative enough, a plastic fork or knife can render an uncommon form which is eyed with jealousy by the next would-be artist. Colors, swirls, fun and joy. And, of course, easy-O.
For oldsters who tipple: Jell-O shots are highly joyful.
