The balloon rocket will show kids how a balloon without direction can become a missile of sorts! This balloon science experiment will help them understand how freedom in Christ means having direction – just like our founding fathers did.
Materials
– One balloon (the longer “airship” balloons work best but the round ones will work too)
– One drinking straw
– 10 to 15 feet of kite string
– Tape
Instructions
1. Tie one end of the string to a doorknob or nail it to the wall for support.
2. Thread the other end of the string through the straw.
3. Tie the loose end of the string to something for support (e.g. chair, leg of table, etc.).
4. Blow up the balloon and pinch the end (don’t tie it), and have a helper tape the balloon to the straw.
5. Let go and watch your rocket zoom!
Explanation
When you blow up the balloon, you are filling it with air. When you release the balloon, the stretched balloon constricts and pushes the air out with great force. This forced-out air propels the balloon across the room like a rocket.
Application
Balloons can remind of us of freedom, in how they bounce around happily, just blowing in the wind. We have that bouncy, happy freedom in Christ, but he calls on us to make sacrifices and to have a bit of direction! Apostle Paul states in Romans 6:22, “But now that you have been set free from sin and have become slaves to God, the benefit you reap leads to holiness, and the result is eternal life.”
Being a slave to God does not have the same meaning as the more common uses of slavery. For one, he is not a taskmaster! He is our heavenly father who never takes advantage. The balloon hooked to the string is a lot like how we are as Christians. We attach ourselves to the Lord and he will get us where we are going, fast and without hesitation! As we celebrate freedom this weekend, let’s remember to hook our new bouncy and happy nature to the back of the Holy Spirit, who will give us direction and a great sense of value!
