Thunder!
To deaden a sound, we use lots light airy and irregular shaped materials... like cotton wool, yet the scientists tell us that
the 'crack' from the bolt of lighting is echoed between all those soft fluffy clouds to produce the loud thunder...
... have they been having me on all these years?

Just think how loud it would be otherwise....... ;D ........speaking of cracks and thunder....... %)

Reference, please?

isn't a soft fluffy cloud made up from lots of hard lumpy drops of water? hit a lake of water at 100mph and its very very hard, speed of sound is 768 mph so it would be even harder, so it would echo.

But audio frequencies range from 20Hz to 20kHz, giving wavelengths from 16.5m to 1.65cm (at the speed of sound of 330 m/s).
This is a range of wavelengths vastly bigger than raindrops: so raindrops shouldn't echo? %)

but its lots of raindrops so it would act like a solid.

A "soft fluffy" solid?

When I was in the Fleet Air Arm we spent a lot of time repairing cloud collision damage %% %% %%
