The mixing wand went "POP" while I was taking a nap. Since things rarely go "POP" in my house, I got up to check it out. The cat was staring at the end of the counter where I leave the mixing wand plugged in & the kitchen had a burnt, acrid electrical smell. After I unplugged it & separated the mixing component from the handle of the device, I looked down inside it & saw a thin wisp of smoke still inside. When I put it down on the counter, I noticed black liquid dripping onto the counter from the end of it. It looks like I need a new mixing wand. It's lucky for me it happened while I was home, instead of maybe burning down my house. After I replace it, I won't be leaving the next one plugged in all the time.
