Egg white solidifies more quickly in hot, salty water than it does in fresh. So a little salt in your water can minimize the mess if your egg springs a leak while cooking. The egg white solidifies when it hits the salt water, sealing up the crack so that the egg doesn’t shoot out a streamer of white.
What happens when you put a boiled egg in salt water?
The large amounts of salt in the ocean cause the salty ocean water to be extremely dense. … For example, an egg floats in salt water because the egg is less dense than the salt water. On the other hand, if an egg is placed in fresh water it sinks to the bottom immediately because the fresh water is less dense.
Do hard-boiled eggs float in saltwater?
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!

How do you tell when boiled eggs are done?
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.
What happens if you boil eggs for an hour?
If you boil it for hours, it becomes rubbery and overcooked. Beyond that, things get a little mysterious. Eggs are full of coiled-up protein molecules. Heating the proteins makes them uncoil and link up with one another to form a three-dimensional lattice, transforming a runny raw egg into a firm, rubbery cooked egg.
How long do hard boiled eggs need to sit in cold water?
Give the eggs at least five minutes in the ice bath before you try to peel them—letting them cool may help make it easier to peel them, but it’s also so you don’t burn your hands.
