How big is a Gnats Chuff?

[MarillionFan]

How would you measure this?

Does the Gnat have to be still or would you attempt to measure it in flight, filming it in motion using a Dyson bladeless fan utilizing the Coanda effect.

No, that is completely wrong, the helicopter uses the third law of motion.

From wikipedia...

"The Coandă effect is the tendency of a fluid jet to be attracted to a nearby surface"

There is no nearby surface on these devices.

Expects churchill to post the first link on google with NOTAR and Coanda in it.

MF - I think your point has been missed!

Not sure about how big it is, but if you were interested in measuring how tight it is, I could point you in the direction of my Brother-in-law's wallet!!
