[xmotohqa] Spinning boiling hot dog

When boiling a floating single hot dog in a small uncovered skillet filled with water, the hot dog periodically flips itself about 180 degrees with a period of about 40 seconds.

Hypothesized mechanism: water trapped in the bottom of hot dog matrix boils, decreasing its density near the bottom. The hot dog flips, bringing that less dense portion to float slightly above the water level, where the vapor cools and condenses within the matrix.
