Some set out to shoot stuff with stuff, others to shoot stuff into stuff, but we chose to blow stuff up. Namely, we decided to explode balloons filled with hydrogen and oxygen internally and measure the speed at which a pendulum placed next to them was propelled away. To accomplish this feat we used a momentary switch to trigger both the spark mechanism (developed by Tim Collier and Bryan Sweeny) and the flash units which in turn were separated by a delay box. Using the two images of the pendulum provided by the flashes and the time between flashes, we were able to calculate the average velocity at a point between the two positions in the images. We reasoned that this average velocity would give a good estimate as to the maximum velocity of the pendulum, since the only deceleration of the pendulum would be due to gravity and this effect is negligible while the pendulum is still traveling horizontally. Using the data we obtained, we found the average maximum velocity of the pendulum to be 27.1 m/s.
