14. Magic Wand
“So you’re actually making mayonnaise IN the mayonnaise jar!”
The Magic Wand is a handheld cutting/blending gadget that you can use instead of your blender/knife/food processor/whisk. In the above infomercial, the Magic Wand is wildly versatile in its applications, making breadcrumbs, mayonnaise, and chocolate mousse. These days, you can do most of this with an immersion blender.
