Tupperware Quick Shake Container 2.5 cups

This shaker/container makes an electric blender unnecessary when the urge for a smoothie, milkshake, or instant pudding arises, a salad needs dressing, or eggs need scrambling. Just pour ingredients into the container, insert the blending wheel with its star-shaped center, snap on the domed seal, grip, and shake. Because the seal is virtually leak-proof, no mess results. The Tupperware seal is also virtually airtight, so you can store leftovers in the refrigerator and they'll remain fresh. Made of rugged plastic, the container holds 16 ounces and is calibrated in both ounces/cups and milliliters on clear strips, which run down the container's sides so you can monitor blending progress. Otherwise, the container comes in Tupperware's classic Sheer Ice color with Red Seal Retail $17
