If your fondness for icy-cold drinks leaves little room in the fridge for last night's leftovers, remember this: Storing soda, beer, and other beverages satisfactorily requires the efficient use of space. Enter Tifan's Easy Stacker. Simple in design—nothing more than a slip-proof silicone strip, inset with ridges and cutouts—the organizer enables you to stack bottles and cans on top of one another. That way, you can capitalize on the full height of the refrigerator shelf and free up a surprising amount of space in the process. Available on Amazon; $9.99 for two.
