I'm actually sort of disappointed Jamie and Adam didn't expend more effort to make a "proper" "square tire." But it seemed all they did was cut the tread off a regular tire and affixed to a square rim. I'd like to see them re-do this only make an ACTUAL, air-filled, tire.
I'm not sure it's possible to make such a tire, I don't think it could hold the air pressure. And even if they could, I think the forceon the edges of the square rims would be so high when the wheel turns, that it wouldn't make much difference.
I was a little surprised about the Pirate myth this week, I thought the swinging would be possible, but that the cage would be far to heavy to climb the wall. Turns out it was the other way round.
