According to Scott Tissue, during the halftime of the SuperBowl (or the Big Game as they call it, to avoid infringing on the NFL's trademark)
"more than 350 million gallons of water will flush through our toilets as an estimated 90 million people use their facilities. That amount of flushing equals seven minutes of water flowing over the Niagara Falls." Actually, they admit that this is a legend, but they've created a website to cash in on the legend:
halftimeflush.com. However, I don't know how they arrive at the figure of 350 million gallons. (I assume they're just making up the figure of 90 million people flushing the toilet.) I thought that the average toilet uses about 2 gallons per flush. In which case, the volume of water used would be closer to 180 million gallons... and so equivalent to only about 3 1/2 minutes of water flowing over Niagara Falls.
But where are they getting their facts about the volume of water flowing over Niagara? According to
this site, 150,000 gallons per second flows over the American Falls, whereas 600,000 per second flows over the Canadian falls. So, assuming that they're talking about the Canadian falls, 350 million gallons of water flushed down the toilet would be equivalent to almost ten minutes of water flowing over Niagara.
Comments
Some of the most efficient toilets need only about 1 gallon of water to flush, but some old ones use as much as 7 gallons. So it's possible that the national average is almost 4 gallons per flush, which would be about 350 million gallons for 90 million flushes.
However, I think they made up the whole thing. How can you know who's flushing at half time? Call everybody on the phone and ask them? Half the people would think it's a crank call and hang up, so you still wouldn't know.
Which is probably an urban legend but it *sounds* so good.
During the wedding of Prince Charles and Diana Spencer there was a surge in demand for electricity.
Caused by kettles being turned on when they went off camera to sign bits of paper.
Measured how?
Surely all you could measure would be that a lot of water was being used. How do you know everybody wasn't taking showers, or washing clothes?
You would have to be pretty determine but my first thought would be to call all cities and find out how much water was used during that time frame.
hmm... If you had those stats you could come up with some pretty influential commercials.
