Dragsters are typically about peak performance on a tarmac drag strip. [Engineering After Hours] took a different tack, though, building a radio-controlled amphibious dragster intended to cross small bodies of water. The build is based on a Traxxas Raptor RC car. However, it’s been heavily reworked from a pickup-like d...

Shortly after the development of the electric light came the light switch, presumably.
