I dreaded having tummy aches as a child. But what I dreaded even more than the occasional stomach ache was the remedy. My dad thought Alka Seltzer was the only solution to a tummy ache. I can still see him putting a glass of water on the table, plop, plop went the tablets into the water and a gentle fizzing would then occur. If you’re my age, you remember the commercial jingle, “Plop, plop, fizz, fizz, oh what a relief it is.” I would hold my nose and try to get the nasty concoction down my throat. I soon decided that I’d rather have the tummy ache than have to drink the Alka Seltzer.
Years later I discovered a much better use for Alka Seltzer. When placed in a film canister with a little water, they make a great show stopping object lesson. Kids NEVER get tired of watching this simple yet effective experiment.
The Experiment: Alka Seltzer Rockets
Supplies: Alka Seltzer, Clear plastic film canister, Warm water
Fill the film canister about ¼ full of water. Break an Alka Seltzer tablet in half and place it inside the canister. Push the cap on the canister quickly and place it upside down on a flat surface. Stand back. A loud popping noise will be followed by the canister hitting the ceiling.
Safety alert: DO NOT STAND LOOKING DOWN AT THE CANISTER. Also, safety glasses should be worn during the experiment.
The Spiritual Connection: Self- Control
Have you ever had someone make fun of you? How did it make you feel? How about someone falsely accuse you of doing something? Did that make you feel angry? Often when we are angry with someone we want to get back at them. We want to repay them for what they have done. What are some of the ways that we repay people? (Allow kids to call out some ways: calling names, hitting, fighting, pouting, talking bad about them behind their backs, yelling at them)
I am going to do an experiment to show what can happen when we get angry and lose control. (Do the experiment.) Anger can build up in us until we just explode with it. When we do that we lose control and do things or say things that we will regret. Is this the way Jesus wants us to react? No, He wants us to forgive others and live in peace with others. We are never to pay back evil with evil. Instead we are to live our lives in an honorable way so that people can see Christ in us.
“Never pay back evil with more evil. Do things in such a way that everyone can see you are honorable. Do all that you can to live in peace with everyone.” Romans 12: 17-18 (NLT)
