Floating egg experiment

Steps To Set Up The Floating Egg Science Experiment
Eventually the egg will float as salt water is denser than fresh water and the egg will weigh less than the water. Egg floating in salt water experiment Why the egg in salt water floats? When the salt is added to the water, it increases the density of the water and hence the density of the egg slowly becomes lesser than the salt water.
Egg in water experiment

This experiment is great in a time when household items are in shortage. With this experiment, all you need is tap water, a cup, salt and an egg or any plastic toy like a Lego piece. Experiment Extensions Another way to make an egg float is to increase the density of the water the egg is in! Once the water becomes denser than the egg, the egg will float.

Floating egg science experiment
Baking Soda Rocket – Experiment
The egg is denser than the fresh water (more molecules per square inch), this causes it to sink. When you start dissolving salt in the water, this is increasing the density (adding more molecules per square inch). Eventually the water becomes denser than the egg causing the egg to float. When you carefully add fresh water again, this fresh water is less dense than the salt water so it floats right on top! Egg and salt experiment Can you make an egg float in water? In this simple science experiment, we take just a few minutes to test the laws of density and discover just how easy it is to make an egg float!

The kids did. We talked about what they thought would happen and then they added each ingredient to the cups one by one making sure to stir them well. To their surprise the oil did not help it to float at all. Next they added salt and were happy to see it helped the egg float at the top of the glass. Floating and sinking eggs – the science bit Based on Lovey’s observation earlier that morning. We discussed what we thought might happen. She predicted that the hard-boiled egg would sink and turn the water hot. (We had cooled it by running cold water over it, but it was still warm.) She predicted that the raw egg would float and turn the water cold.
