What would happen if you combined Tesla coils and Nerf guns together: You get a Tesla coil Nerf gun. That's what Rob Flickenger invented for himself. Here's how he and Rusty Oliver of the HazardFactory put together one:
He made an aluminum version of the plastic toy. He gathered cans, scrap metal, and even a bicycle fender and melted it all down. Then he and Oliver created a cast of the Nerf gun out of sand and clay and poured in the molten aluminum. After it hardened, Flickenger milled excess metal from the interior using a CNC machine and cleaned up the edges with a rotary tool.
