The estimated flow rate of the Deep Horizon spill keeps going up. The current low estimate is a flow rate of 25,000 barrels a day. But what, exactly, does that look like? 25,000 of anything is a lot, but exactly how many? Fortunately, some kind folks have used gaming technology to simulate 25,000 barrels stacked around a pillar 15,000 feet high, and then group by group falling to the ground.
