I know a bit about physics and I can say that for that to happen there are no less than 100 variables required to be filled in order to repete that shot. The most crucial are ambient air temperature, air pressure in the balloon, thickness of balloon wall, sharpness of fieldpoint tip, ambient humidity, surface moisture on the point and arrow shaft(if any) and seep of arrow, arrow placement. I think those alone would make it impossible for MythBusters to duplicate the results.
Still "WOW" is appropriate; but would you believe I have not only seen this before but done it myself?
