We did an experiment on density
What happens when you drop an egg into an ordinary glass of water and an egg into salt water?
1.The egg in the ordinary glass of water sank to the bottom because it wasn't dense enough for the egg to travel through the water.
2.The egg in the salt water floated because the water became dense and the egg couldn't travel through the water because of the density.
This happens because saltwater is denser or heavier than ordinary water. It was easier for the egg to float
