For example, watermelon juice. Deliciously watery and subtly sweet, this drink should've hit the jackpot years ago. Yet it's not even mainstream. And think about it, it's not like it's super hard to juice a watermelon.
Strawberry juice. I suppose it'd be harder to juice strawberries because of their seeds, but if they can squeeze not-very-juicy apples, then strawberries should be a cinch.
I feel like these would make delicious juices. I should open a juice factory. You just wait and see...
