A collage Lab partner did something similar.. On a bread board he
plugged a quarter watt 5 ohm resistor from +5v to ground. He too, was
off by a pin. The resistor  was glowing bright red in about a second.
Now why did it take Edison so long to invent the light bulb? Oh as for
the resistor. Well After it cooled down we check its resistance... It
had become about 100 ohms or so.
