I found this recipe on Kraft Foods.com for Football Field Gelatin but I was thinking this would make an unique centerpiece for your table at your Super Bowl party. Its easy and inexpensive too.
Football Field Gelatin
STIR boiling water into dry gelatin mixes in large bowl at least 2 min. until completely dissolved. Stir in cold water. Pour into 13x9-inch pan.
REFRIGERATE 4 hours or until firm.
USE whipped topping to draw "yard lines" on gelatin. Arrange toy football figures and decorations on gelatin. Store in refrigerator.
