Looking for something to do? Need extra security around the house or shop? Robot dogs with flamethrowers attached to their head are now a thing. A company called Throwflame is selling one called the "Thermonator" for $9,400. The website says they're legal in all 50 states. You just need a special permit in California and Maryland. They're not pushing the guard dog angle, but they do list eight different things it's perfect for, controlled burns . . . ice and snow removal . . . clearing weeds . . . pyrotechnics or entertainment . . . and also pest removal. You operate it over WiFi or Bluetooth with a remote control, and it can shoot flames up to 30 feet.
