In a large bowl, whisk together the Jell-o and boiling water for about 2 minutes. The Jell-o should be completely dissolved. Whisk in the cold water until combined. Add in the whipped topping and mix until smooth and no streaks remain. Refrigerate the mixture for 30-45 minutes until slightly thickened.
