Floating Egg Science Experiment

The Floating Egg


Eggs sink in regular tap water, but creating a saltwater solution… that’s an egg-citingly different story.

We’ve shown you how different sodas will either sink or swim in plain tap water, but what’s the deal with eggs? Drop as many eggs into plain tap water as you want, but they’ll all sink to the bottom. In the Floating Egg experiment, we’ll show you how the addition of something as simple as table salt, can drastically alter what happens to eggs in water

Supplies Needed for the Floating Egg Science Experiment

  • 2 Eggs
  • 2 Tall Drinking Glass
  • Salt
  • Water

Floating Egg Science Experiment Instructions

Step 1- Fill One Glass with Water

Step 1 – Fill a tall drinking glass about 3/4 full of water

Step 3 - Watch the Egg Sink

Step 2 – Place the egg into the glass of watch and watch it sink…

But this is the Floating Egg Experiment, right?

Step 4 - Fill Second Glass with Water

Step 3 – Fill another tall drinking glass about 3/4 full of water

Step 5 - Add Salt to Water

Step 4 – Add 3 Tablespoons of Salt and stir until combined

Step 7 - Watch the Egg Float

Step 5 – Place the egg into the glass and watch it float

How Does the Floating Egg  Science Experiment Work

The egg will sink in regular tap water because the density of the water is less than the density of the egg itself. Adding sale to the water increases it’s density making it more dense than the egg. Therefore the egg will float in the salt water.

I hope you enjoyed the experiment.  Here’s some printable instructions.

Floating Egg Experiment Steps

I am scientist

I am scientist is a result of small effort to make huge impact on children. To stimulate the curiosity of young scientist towards science. Each idea will start with a experiment followed by reasoning the result , scientific learning, vocabulary (recap the big words used), useful reference website and books, along with free downloadable worksheets.
