Floating egg Brain teasers and fun science tricks

Step 1: Every experienced homemaker knows that if an egg floats in water it’s not fit to eat. Fresh eggs will always sink. Conclusion: an egg is denser than water. Does that really mean that it’s impossible to make a fresh egg float?

Step 2: It’s possible, of course. Saltwater is heavier than fresh, and you can dissolve enough salt into water to make an egg float.

Step 3: Try experimenting. With just the right amount of salt, you can even make the egg float underwater–not just on the surface!
