To make the egg float, we have to make the water more dense by adding salt. For 1 cup of water, adding 3 tbsp. of salt should be about enough to make the egg float.

Jupiter gets, on average, about 3.4 times the solar radiation per square meter than Saturn gets.

The Atmosphere of Saturn Saturn is farther from the Sun, and colder. Makes the bands less chemically complex, and so more subtle & less colorful than Jupiter’s.

You can drop your hard-boiled egg in and it will sink to the bottom of the first layer, but float on top of the salt water! The egg is denser than tap water, so it sinks. Adding salt water to the water makes the water denser than the egg. This causes the egg to float!

If the egg sinks, it is fresh. If it tilts upwards or even floats, it is old. This is because as an egg ages, the small air pocket inside it grows larger as water is released and replaced by air. If the air pocket becomes large enough, the egg may float.

If the egg sinks or stays at the bottom, it is still fresh. An older egg will either stand on its end or float. The float test works because air builds up inside the egg as it ages, and this increases its buoyancy. However, an egg that floats may still be safe to eat.

Old eggs tend to float, whether raw or boiled, as they have lost moisture and their density has decreased. Fresh eggs sink in water, whether raw or hard boiled. If it is cracked, but still has substance inside, then it’s boiled or cooked.

Refrigeration is key to keeping your hard-boiled eggs safe and fresh. Hard-boiled eggs should be stored in the fridge within two hours of boiling and kept on an inside shelf instead of in the door. Avoid peeling hard-boiled eggs until you are ready to eat or cook with them.

If you’re wondering how to tell an egg is hard boiled, set it on the counter and give a quick spin. Once it’s moving, tap your finger on it to stop the spinning. Eggs that are cooked will spin easily and rapidly and stop quickly.

Tip: Just place the egg on a hard surface, like the counter, and spin it like a top. As it’s spinning, grab it with your fingers ever-so-briefly and immediately let go. If it keeps spinning, it’s raw. If it stops dead, it’s boiled.

When it comes to boiling eggs, the biggest problem is that people can easily over-cook them, leading to a dark green color around the yolk, and a somewhat sulphuric taste.

Put the pot over high heat and bring to a boil. Once the water is at a rolling boil, turn off the heat and cover the pot with the lid. Allow the eggs to sit in the hot water for the following times according to the desired doneness: 3 minutes for SOFT boiled; 6 minutes for MEDIUM boiled; 12 minutes for HARD boiled.

An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant. This means the egg is older, but it may be perfectly safe to use. A spoiled egg will have an unpleasant odor when you break open the shell, either when raw or cooked.
