How To: Create A Metal Detector In this video, I will show you how to create a metal detector out of just two household items for under $20 US dollars. Please note that I said you can use a penny with the metal detector but of course you can't because it's not metal. DUHH, lol What You Will Need: 1. A calculator 2. A walkie talkie 3. Something metal
