Always enjoyed that advert - very cleverly done and no computer trickery either.

I don't think that the silencer would roll like that from so little height.

A clip on how the ad was made - without any CGI:

The Making Of Honda Cog - YouTube

If by "without any CGI" they mean they actually set that up, then...er...pull the other one.

It might be in a different universe where our boring laws of physics don't apply

You might not want to be believe it but it was all done in one take without CGI.

Aaah. They're chocked underneath, so presumably weighted at the top. They'll need rebalancing.

You could also tilt the reference frame to apparently defy gravity.

That wouldný be CGI either.

But it would still be fake.

No doubt parts have been messed with to get them to do what they need to do - but the point is that no CGI was required and it was all done for real...despite a few posters finding that hard to believe for some reason.
