So he opens the drain, and then all of a sudden, water starts draining out at a much higher rate, at 20 gallons per minute, but then that decreases. And so we could think about physically why that might decrease. Maybe there was just less pressure or whatever. We're not gonna go into the physics of it, but we're just gonna take this chart as fact. But the rate at which the water drains decreases all the way to the 60th minute, which is 40 minutes after he opened the drain. 60th minute, all of the water was drained. All of the water was actually drained out.
