One of the things I wanted to test was the famous balloon shot. To take a picture exactly when the balloon raptures. This turned out to be a bit more complex than I had thought. One thing was simply the physics involved. Although I am an engineer at hart I had  never really read up on balloons and what made them pop. It turns out that the big sound bang does not come from the air rushing out of the balloon but rather from the latex accelerating and passing the speed of sound barrier. The problem for me was that using the sound from the popping balloon to trigger the flash leaves very little time.
