Bought this little thing called the Aqua Zinger back in October while shopping with my besties, and turns out that I like it more than expected.
I fill it with whatever fruit combos I have on hand. This day I use pomegranates, blueberries, and juice from a meyer lemon.
The fruit goes in the bottom canister (a lid goes over the bottom canister that serves as a strainer and with teeth, if you will, that as turned against the teeth below to break up the fruit and expel the juices)
Then you fill it with water, shake it well, and put in the fridge for a few hours.
I purchased mine from Brookstone.
