120VAC meets a hot dog, Interesting science results.

Hot dogs are essentially resistors, and when a voltage is applied across them, they dissipate power as heat. In order to better understand the nature of their resistivity, I cooked hot dogs electrically and recorded the times and temperatures using an Arduino.
To make sure the hot dogs cooked reasonable quickly, wall voltage was applied (120V AC). The Arduino took temperature readings from a type K thermocouple wedged inside the hot dog and used a relay to kill the circuit once the meat was fully cooked. Google revealed that 150°f was a fine temperature for a cooked hot dog. After cooking and logging data, the potentially carcinogenic ends of the hot dog were cut off and the meat was tested for tastiness.
