Egg, Salt and Water Trick (OBJECT LESSON)

This object lesson teaches that it isn’t enough to just be Christian in this world. We need to have “saltiness” so that we help to make life better, heal those who are hurting and save those who are lost. This lesson uses a science experiment in which you can make an egg float by adding salt to water. The salt increases the density of the water, making the egg more buoyant.
