A New Spray Tool for Fresh Citrus Juice Love the convenience of those citrus-shaped spray bottles of lemon and lime juice, but also want the juice to be fresh? Both are possible with Stem, a spray nozzle that you insert into the fruit. Press the plunger to spritz fresh juice (even orange or grapefruit) onto fish, into a cocktail or over a salad. Stem is the latest product from Quirky, a collaborative New York company that specializes in developing "Why didn't I think of that?" gadgets. Would-be inventors who join the Quirky community (easily done online at quirky.com) can submit ideas, and if they win the approval of other members, the company's design and production team takes over. Quirky also handles distribution and shares profits with the inventor. Stem citrus juice sprayer, made of food-safe polypropylene, is $4.99 from quirky.com and Target, target.com.
