Hey steven. Pull up your pants and get a belt.

You were testing the balls wrong. punting distance is important, but what is more important is the hang time (how long it stays in the air) to allow your team to get down and prevent a return. I would like you to revisit this myth and test which ball stays in the air longer.

A lighter football should have higher initial speed from the same kick but in your experiment the initial speeds were identical.

I agree with anthony on this one I just saw this episode and was expecting hang time to be tested yet distance was the only thing tested, if distance was the case u could try filling it with a heavier gas and attempt to test newtons law

Whoops, I realised I forgot to multiply by Pi. That would make the mass of the cylinder of air about 8649 tonnes. So it’s true then! :)

The Eiffel tower is 293 meters high and the legs are 125 meters apart. The widest point would be the diagonal between the legs, which would be around 177 meters.
At these measurements a cylinder around the tower would have a volume of 293 x (177 / 2)^2 = 2294849 cubic meters.
The weight of air at around sea level is about 1.2 Kg/M^3, which would give the cylinder a mass of around 2753 metric tonnes.
Wikipedia tells us that the metal parts of the tower alone weigh 7300 tonnes. Add another 3000 tonnes for the concrete feet.
So they’re about a factor of 3 off. Still a lot closer than I would have guessed!

They introduced Hang Time but in the aired episode, they did not show any measurements of Hang Time. In this Myth, the hang-time is far more significant (than linear kick yardage) as with American Football when a ball is punted with a good high loft, it gives the punting team extra time to assemble downfield to defend against the Punt Return. The Mythbusters are my heroes … but they missed the ball on this Myth.
