Experiment - NT: Life of Jesus: Calling of Levi - Mix cold / hot water
A fun experiment about the Bible story of Jesus calling Levi and eating with sinners
A simple but very impressive experiment - do cold and hot water mix, or do they keep separate, just as the pharisees wanted to keep separate from sinners? Jesus challenged societal norms and showed God's inclusive love and acceptance of all, just as the waters eventually mix.
This idea is part of a complete Sunday school lesson containing 14 ideas on Levi being called by Jesus in Mark 2: 13-17 and Luke 5: 27-32.
View the idea below...
What you need:
two identical glass jars
red and blue (food) colouring
baking dish / transparent tray
Jesus calls Levi, a despised tax collector, to be his disciple and eats with him and other sinners, challenging societal norms and showing God's inclusive love and acceptance of all. We can find this Bible story in Mark 2: 13 - 17.
The Pharisees and law teachers spoke with outrage of Jesus mixing among evil people. They would never do this. They were more like today's experiment. Or could things be different?
Put one glass jar in a dish or transparent tray. Fill this jar with very cold water. Stir in a drop of blue dye and fill it to the brim.
Pour hot water from the tap into the other jar. Stir a drop of red dye into this and fill it to the brim.
Place the piece of card on the red jar and gently press it down. Keep pressing the card and quickly turn the jar over. The card will keep the water in the jar.
Put the red jar upside down on the blue jar and gently pull the cardboard card away.
What happens? Do you see the colours mixing?
Definitely not at first. This is because the cold water has a higher density than the hot red water.
The cold water looks like the Pharisees. They really weren't going to mix with those bad people.
Jesus has no problem with this at all. He came precisely for these kinds of people. He is happy to mix with everyone.
What happens, do you think, if we leave these two glasses for a while?
As the hot water cools down and the cold water gets warmer, the water will turn purple.
Look again at the two jars in about 20 minutes.
