Just 5 or 10 minutes in a bowl full of warm water â hot water may cause the egg shells to crack â will take the chill off of your eggs. Recipes that call for egg whites alone often call for them to be at room temperature. Eggs are, however, much easier to separate when they are cold.
While these datums are based on observations, two others are based on predictions: Highest Astronomical Tide (HAT) is the highest water level predicted and Lowest Astronomical Tide (LAT) is the lowest water level predicted relative to MSL over the NTDE.hile these datums are based on observations, two others are based on predictions: Highest Astronomical Tide (HAT) is the highest water level predicted and Lowest Astronomical Tide (LAT) is the lowest water level predicted relative to MSL over the NTDE.
So the period from one high tide to the next is about 12 hours 25 minutes. When the sun, moon and earth all line up at new (as in the picture) or full moon then we get the highest (and indeed lowest) tides which are called 'spring' tides (nothing to do with the time of year!).
