San Diego residents got a little more bang for their buck on the Fourth of July when a technical glitch set off an entire fireworks show at once.

The Big Bay Boom fireworks display, which was supposed to take 18 minutes, lasted for just 30 seconds.

According to ABC News, five barges worth of fireworks began bursting at the same time due to a computer problem. The resulting fireballs were pretty impressive, albeit short.
