Surprise, surprise, Brigham chose a project that uses fire!!!! This year he did a "fireproof balloon" project. Here are some great photos of the experiment.
 |
| Filling the first with air. |
 |
| The air filled balloon popped the fastest after only a few seconds. |
 |
| This water filled balloon didn't pop at all even after 5 minutes of having the flame under it. |
 |
| The sand filled balloon actually caught fire, but didn't pop, it just bured a hole for the sand the drop out and then extinguished itself. |
Briggs had a great time with this one. It was amazing what different substances will do to change the character of a balloon.
