Yeah bad title and to come worse science. What is the floatiest thing? Probably pollen or something. Floaty things have a limited life at sea cos they run into countries, but what about floaty things in the air.
I’d go for spiderweb.
ballooning spiders.

Sounds fair.
floatiest thing would be hydrogen and helium particles which actually escape the earth’s atmosphere …
;-)
particles?
yeah, particles. as in atomic particles, subatomic particles etc.

I was going to say that, so instead I’ll say the floatiest living thing is an albatross.
is that the seabird flavoured one?

They do good jobs as well. Six months without land fall. They do eat though, and they do settle down and eat, so they are not that floaty.

Swifts are less likely to alight.
the thing with birds is that they input energy to keep aloft. without that they wouldn’t stay up all that long.

They do have stuff like hollow bones to assist.

True, but the albatross does get a lot of that energy from the air, rather than from wing flapping, so I think that should count as floaty.

maybe the swift or the tern could vie for that.
Might not be the floatiest, but the best tasting are the yeasts that help in the fermentation of Lambic beers.

bacteria…..help make clouds

Swifts are the most aerial of birds. Larger species are amongst the fastest fliers in the animal kingdom, with the white-throated needletail having been reported flying at up to 169 km/h (105 mph). Even the common swift can cruise at a maximum speed of 31 metres per second (112 km/h, 70 mph). In a single year the common swift can cover at least 200,000 km.

Swifts spend most of their time in flight.
The Pacific swift has a very large range, exceeding 10,000,000 km2 (3,800,000 mi2). Its population is unknown, although it is common throughout its breeding range with no evidence of any decline.

Dust ejected into the atmosphere from asteroid strikes
Human farts? they are very fast too.

Swifts will light just fine if you dunk them in petrol first…

This is really quite a subtle question. Large particles fall out of the air under the force of gravity. The smallest particles (such as atoms) are also are removed from the air fairly quickly due to the combination of Brownian motion and higher order electrostatic attraction. There is an intermediate size where the deposition rate is smallest.
The objects that float in the air most are particles with a diameter of 0.2 to 0.3 microns (i.e. 200 to 300 nanometres).
The rate at which these floatiest particles deposit on the ground depends on the atmospheric turbulence and can range from 0.015 mm/sec to 0.5 mm/sec.
