How many lasers does it take to destroy 100 black balloons? If you're a mad scientist, or you happen to have a custom laser modified from a Blu-ray burner drive, all you need is: one.

Interesting is that as the laser travels farther, the longer it takes for the balloons to pop, taking a total of eight seconds for all of them to be annihilated. So don't go having any bright ideas about world domination, yet.
