I don't think Green Milk is gross, when I was in school, the school used to give us green milk. That mom is just not fun! But there is green Kool-Aide, I am sure there are other green fruit drinks out there. And if you are taking it to the preschool, you could make a green drink in a bucket for them to pour into cups.
Here is an idea:
Lucky Lime Drinks
Put some scoops of lime sherbet in an ice cream bucket. Pour 7Up over the sherbet. Add a dollop of whipped cream, green sugar sprinkles and a green maraschino cherry to all the cups after it is poured.
