The ones were you hear the F1 whizz past, and the person/s in the ads get the sudden voilent blast of air.

How could you induce such a sudden forceful blast like that ?

Dont bother with the 'beans or Indian food' gags, I am perplexed......

Thanks in advance.

Easy! Just pressurise a vessel to about 50psi then release quickly through a largish (2") valve.

Beans and indian food.

A large and powerful fan, hmmm.

How could it just be on...BLAST....then off in a blink ?

Remember theres not a flicker from his newspaper, then BOOM he's blasted, then a split second later.....nothing.

They probably crank up a large fan and swing it round passing the bloke on the way. Some of those fans they use are bloody powerful!

Helicopter in the next room.

Open the window, instant air.

Problem solved!!

I thought it was done by getting an F1 to come wizzing past out of camera shot ??

Its a series of very thin cables attached to most of the things in the frame. Look carefully and not everything moves at the same time.

Then they have a complex system of winches that pull it all together.
