Mr. Spectaculo, famous magician AND acrobat, once explained to a crowd of people that he could walk down a kilometre of cement sidewalk on his hands. After announcing this claim, he did a handstand, and waddled on down the sidewalk to the other end. Even after this amazing feat, a man came up to the crowd and announced something that completely disproved him. What did he say?

Ooh, ooh, I know this one!  Call on me please! *waves hand wildly*

If he's just done what he said he was going to do, I don't see how he can be disproved.

Unless there's some fiddly detail in what he said vs what he did. Like the sidewalk actually not being cement, but tarmac or concrete or whatever.

That or "waddled on down to the other end" didn't involve a kilometre distance of sidewalk...

Right again. Sidewalks aren't made out of cement, they're made out of concete. (or tarmac)

Oy. +1 SK.

I don't get this? can someone please explain?   Concrete is made from cement... So it's one and the same thing?.. If you have a piece of bread and put it in a toaster it becomes toast... However you can still call it bread..

That's arguable, I suppose, but he did say what I was looking for. If it's such a big deal I could get rid of the point.

It's almost like my riddles shouldn't count for anything, they're apparently obscenely easy.

Jake, why didn't you just say so if you knew the answer?

Concrete is made from cement, but cement is not the only thing in concrete.

Quote: "CEMENT: "a powder of alumina, silica, lime, iron oxide, and magnesium oxide burned together in a kiln and finely pulverized and used as an ingredient of mortar and concrete."

CONCRETE: "...a hard strong building material made by mixing a cementing material (as portland cement) and a mineral aggregate (as sand and gravel) with sufficient water to cause the cement to set and bind the entire mass."

And that is why cement is not concrete. The end.

clap clap.

LOL!
