Universal Law of Burner Attention:
The amount of attention paid to a gas burner on which one is making tea is inversely proportional to the amount of heating received by the cooking pot.
Simply put:
Paying attention to a gas burner leads to no heat reaching the vessel.
Corollary to the Law of Burner Attention:
When you look away for one split second, the tea on the burner boils over.
