This object lesson helps children understand that God will help them get through difficult times and situations. He never allows us to go through more than we can bear, and He never leaves us alone.
The lesson uses a little science. You will put a skewer through a balloon without popping it, because the strands of polymer in the rubber will stretch around the skewer to make a seal.
The lesson is simple enough for even grade school children to do it themselves successfully with a little guidance.
