Balloon Car Troubleshooting Chart
Below is an example of a troubleshooting chart to be developed in a class meeting with input from students.
| Issue: Balloon won’t hold air | |
| Cause | Fix |
| Balloon is broken | Use a new balloon |
| Leaks when taped to straw | Use more tape or tighten rubber band |
| Can’t pinch straw easily after balloon is blown up | Use longer straw or move balloon and straw further back |
