All the water used in the experiment came from the same source, the same vessel was used for boiling water both on the stove and in the microwave, and all three types of water were stored in identical containers.
Peeled hard boiled eggs can be stored in the refrigerator in a bowl of cold water to cover for about 1 week (change the water daily). SAFETY NOTE: It is not safe to leave hard boiled eggs (including those in their shells) out at room temperature for long (and especially in hot water).
1. Hard boiled eggs can last seven days in the fridge. That is, if they are unpeeled. If they are peeled, they can last five days in the refrigerator past the date they were boiled. 2. How you store your eggs is important. In a sealed container and in the fridge is ideal.
