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.

- Two drinking glasses
- Two raw eggs
- Table salt
Fill one of the drinking glasses almost to the top with plain tap water.

Fill the second drinking glass half-full with water.
Add four tablespoons of table salt to the water, and stir. Fill the rest of the cup with water, almost to the top.
Gently place the second egg into the saltwater solution…
