Prepare 1 package of blue gelatin Jello. Pour Jello into 6 clear, plastic cups. Add a couple of gummy dolphins into each cup. Refrigerate until Jello is ready. Take 10 Graham Crackers and place into ziploc bag. Smash crackers until ghet look like sand. Sprinkle "sand" on top of Jello cups, but leave half of the cup blue so that it looks like half sand and half water. Add drink umbrellas toeach cup and enjoy! This is a great recipe for summer birthday parties too!
