That's a great and terrifying idea. When that inevitably happens, you'll then have a couple of 13-year-olds: one dead, and one shell-shocked kid in disbelief that a stupid prank idea he cooked up in 60 seconds is now claimed as the root cause why someone was killed. That one may be charged with a crime or sued, though the district who installed this idiotic thing is really to blame.
