Preheat oven to 350°F (175°C). Grease a 9×13-inch baking pan. In a bowl, mix the cake mix, water, oil, and egg whites according to the package instructions. Pour into the prepared pan and bake for 25–30 minutes or until a toothpick inserted in the center comes out clean.

Let the cake cool completely in the pan. While it cools, dissolve the lime gelatin in 1 cup boiling water. Stir in 1/2 cup cold water and set aside.

Using a fork, poke holes all over the cake, about every 1/2 inch. Slowly pour the gelatin mixture over the cake, letting it seep into the holes. Refrigerate for at least 1 hour to set.
