Fill the popsicle molds halfway full with root beer. Set aside.

Combine the Cool Whip and yogurt together in a bowl. Place 1 tablespoon of the mixture into each mold along with the root beer. The root beer will bubble up like a float.

Fill the molds to 3/4 of the way full with more root beer. Add another tablespoon of Cool Whip. Take a knife and mix the Cool Whip into the root beer.

Fill the rest of the way with root beer. Place the popsicle sticks in and freeze for 4 hours.

Remove from the freezer and run the popsicles under hot water for 5 seconds and then pop out and enjoy!
