Blend the watermelon and juice until smooth then add the mint and stir to combine. Pour the juice back into clean and empty Clover Krush bottles - filling 3/4 of the way and freeze. Remove from the freezer every now and then and shake hard then refreeze until the juice is a slushy consistency.
Serve with straws on a hot sunny day.
