First off we had to compete to see who could get theirs to not crack, using only straws tape and paper. I felt like I was on zoom. After deciding that our eggs we secure enough we dropped them off the second story balcony. They didn't appear to break. That was when the launcher came out.
After they didn't crack from launching them down the street it was time to launch them directly to the wall. This time they did crack and not only crack they exploded everywhere, which made it all the better. Lesson: bored? get a water balloon launcher... the possibilities are endless.
