Heat the Eggs

Place the pot over medium-high heat, without a lid, and allow it to come to a rolling boil, which is indicated by large, vigorous bubbles. Bringing the pot to a boil without a lid will slow down the heating process and reduce the likelihood of the shells cracking.

You may see streams of bubbles coming out of the eggs as they heat. This is caused by the pocket of air at the bottom of each egg, which expands as it's heated. The expanding air will escape through the tiny pores in the egg's shell and appear as a trail or stream of bubbles. If the eggs heat too quickly, the air will expand faster than it can escape and the pressure will cause the shell to crack open.

As soon as the pot reaches a full boil, remove it from the heat.
