Use the density difference in saltwater and freshwater to suspend an egg in the middle of a
solution.

▶️ How to do the floating egg experiment:
Step 1: Fill a tall vase halfway with room temperature water.
Step 2: Mix in enough salt to create a saturated solution. I used about ½ cup.
Step 3: Stir the saltwater solution until dissolved.
Step 4: Pour the saltwater solution into a tall vase, filling it about ½ way.
Step 5: Wait 1-2 hours until the salt water is no longer cloudy, and any excess salt collects at the bottom.
Step 6: Pour warm, freshwater carefully into the vase to fill it up. Be sure to use warm water. The goal is to keep the saltwater on the bottom and the fresh water on top.
Step 7: Drop an egg into the vase and observe.
▶️ How the floating egg in water experiment works:
When you drop an egg in a saturated solution of salt water, it rests on the surface because the egg itself is less dense than the saltwater. However, when you drop an egg into warm, freshwater the egg will sink to the bottom because the egg is denser than the freshwater. Since our container holds a layer of saturated saltwater is resting under a layer of warm freshwater, the egg is suspended right in between these two layers because of its density.
