The oil well that’s been leakig for well over a month now, polluting the seas around Florida and the Gulf of Mexico.

Top kill is basically squirting stuff into the hole and hope it gets bunged up.

Starting with a heavy, clay based mud pumped into the well head’s “blow out preventer”, a set of valves that should have sealed the leak, the flow should be stopped. If that isn’t totally successful they can also add “junk” to the mud, like golf balls which will jam up the pipe and give the mud something to cling to.
