Soda-Mentos Geyser Bible Science Experiment

How to Play

Place the bottle of soda in the middle of a field.
Make sure it is stable and will not topple easily.

Carefully open the bottle.

Drop a few Mentos (try 5 to 8) into the bottle all at the same time.

Run away as quickly as you can!
Watch the soda erupt into a huge geyser.

Tips

Most people prefer diet soda because it produces a higher geyser. They are also sugar free and easier to clean.

To easily drop multiple Mentos into the bottle at the same time you can roll a piece of card or paper into a paper tube that can fit inside the mouth of the bottle. The Mentos should fit loosely inside this holder.

Read
Luke 15:7

7. In this passage, why was there rejoicing in heaven?

Say
The Bible tells us that God loves us and wants us to be with him forever and ever.
But we cannot be with God because we have all sinned. (Isaiah 59:2, Romans 6:23)
We have all done things that are wrong. (Romans 3:23)

The punishment for our sins is separation from God.
That is why God sent his Son, Jesus, to die on the cross so that all our sins can be forgiven. (Romans 5:8)
And on the third day, he became alive again! (Acts 13:30,31)

If we believe in Jesus, we can now have a relationship with God.
We can become children of God. We can call God our Father.
And we can one day be with God in heaven! (John 1:12, 1 John 1:9)

This is the reason why there is rejoicing in heaven whenever one of us repents of our sins and puts our faith in Jesus.

Discuss
8. Do you know what it means to repent?

Say
Repentance is when we decide to turn away from our sins and follow Jesus: confess our sins, ask God for forgiveness, put our faith in Jesus and invite Jesus into our lives to help us turn away from sin.

Discuss
9. Have you repented of your sins and put your faith in Jesus?
If yes… Do you know that heaven rejoiced over you when you did this?
If no… Would you like to do this now?

Say
Here’s a prayer you can say right now:
Dear Jesus,
Thank you for loving me. I know that I have sinned. I have done things that are wrong. I believe that you died on the cross to take the punishment for my sins. Please forgive all of my sins. Please come into my life and help me turn away from doing wrong. Thank you that because you took the punishment for my sins, I can have a relationship with you now and will one day be with you in heaven.
In Jesus’ name I pray, Amen

Conclude
If you have just said this prayer, heaven is rejoicing over you right now because you now have a special relationship with God and you can one day be with God in heaven!
It is important that you grow in your relationship with Jesus. You can do this by:
– Talking to God
– Reading God’s word, the Bible, and
– Obeying him
