Make a regular egg float in a beaker as if by magic.
What You Need:
- 250 ml flask
- 250 ml beaker
- stir rod
- raw egg
What You Do:
- Measure 10 heaping scoops of salt into a 250 ml glass flask. Add approximately 100 ml of water and stir until the salt is dissolved. There may be some left at the bottom of the flask; this is fine.
- Add approximately 150 ml water to the beaker. Put the funnel inside the beaker, making sure the bottom of the funnel is at the bottom of the beaker, with the spout pointed towards one of the sides.
- Slowly pour the salt solution into the funnel, until the water level in the 250 ml beaker is around 200 ml. Carefully remove the funnel.
- Use the spatula to carefully add the egg to the beaker, taking care not to mix the water much.
The separate layers formed because salt water is denser than pure water. Fresh water has a density of about 1.0 gram per ml of volume. Matter with higher density will sink in water; matter with lower density will float on top.The density of an egg is between that of water and salt water, so in your beaker, the egg balanced between the two layers.
