Detecting the POP! is doomed to failure without knowing the specifics of the audio sensor. It may be protected from low frequency sounds ( like any proper mic would be ) or the op-amp may be inverting the signal, so that you miss the leading pressure wave.

Use a solenoid ( electromagnet ) to suspend the dart, when the solenoid de-energizes, under the control of your arduino, the dart falls per Newton, and probably some other people.

Even better than a dart would be a pin, much more dramatic and nobody will guess you used a magnetic release. They will think you have the patience of Job to drop that pin perfectly vertically.  Electromagnetic release is also useful for many other very wonderful setups, so worth building it.
