Beat the whipping cream with an electric mixer until stiff peaks forms.
In a separate bowl, combine the condensed milk and vanilla extract. Add a large dollop of whipped cream and mix until combined. Add the remaining whipped cream and gently fold until combined.
Divide the mixture into 2 bowls. Dye one bowl green and one bowl blue.
Spoon dollops of each color into a plastic Tupperware container. We recommend using a clear Tupperware container, so that you can see the pattern from the outside!
Seal the Tupperware container closed, then freeze for 6 hours, or until stiff.
Scoop with an ice cream scoop to create little ice cream globes! Enjoy!
