When the zombies eventually come and find me in my kitchen, I will skip over the firearm, sword, or bat in favor of arming myself with an immersion blender. In the wrong (or right) hands, you could efficiently turn flesh to mincemeat in a pulse, so take heed. When you’re done mixing, take your finger from the trigger and unplug it before you put it aside. And never turn it on unless the business end is submerged in your food in a deep container so you don’t accidentally spray 180 °F tomato sauce across the walls or, you know, your children’s faces. This should be common sense, but forewarned is forearmed.
