Jello Mousse

My sister pointed out to me this recipe and I'm so glad she did.  See, she doesn't like things simple; she likes to tweak them here and there, and this is one of them.  This is such a simple recipe, yet the result is absolutely delicious!  It's a hit with everybody!  Enjoy!
-1 1/2 cups boiling water
-1 (3 oz) package of your favorite jello flavor (I used grape)
-1 (8 oz) tube cool whip, thawed
In a bowl, mix boiling water and jello powder.  Mix for 2 minutes.  Whisk in manually the cool whip.  Whisk until well combined.  Cover and place in the fridge for 6-8 hours or until set.  Enjoy!
