In this idea we will show you how you can use the experiment of the Indestructible Sandwich Bag to tell the Bible story of Moses hitting the rock in anger when the Israelites keep complaining about the lack of water. Instead of listening and obeying the order God gave him to speak to the rock, Moses relies on his past experience, and hits the rock. Water flows, but there is also a judgement from God.
You can use this experiment within a school assembly, a RE lesson, as a preaching illustration, a children's moment in church and of course in any Biblical teaching setting.
