Hi,
some thistle down can be quite uniform in its release. They shoot up up
into the air one by one very suddenly. It's not perfectly uniform but it's
more uniform than say a Dandelion as Dandelion seeds are much lighter.
I don't know if you can 'see' what I mean but the seed catches the wind and
shoots up. It may be only a few seeds go but they do seem to fly upwards. I
guess they have to get a certain wind velocity to carry them.
