I am always looking for cool healthy gadgets to make being healthy just a little easier on my lifestyle.
This Sundesa Blender Bottle ($8.50) is a 28 oz. plastic bottle with a surgical stainless steel ball that you drop into the cup with your ingredients and shake. The cool part is that the ball stays in the cup until the ingredients are emptied. It's better than just shaking ingredients in a cup because the ball really mixes everything up (it even gets rid of lumps). Not only is the Blender Bottle great for making nutrition shakes, I'm thinking you can also use it to make healthy salad dressings, smoothies and even omelets.
Buy it from Amazon.com. Oh, and FYI, don't get your heart set on a certain color because the seller will randomly choose a color for you.
