LOL!,...yeah, the stuff certainly doesn't weigh anything, so alot of it is BIGGG!..LOL!
Man!, Many years ago, the construction company I used to work for had literally HUNDREDS of huge bags of the stuff that we poured down every single block cell before we formed the tie-beam of this giant multi-million dollar home to insulate it with.
That stuff got blown all over the place in the slightest wind, and was stuck all over us because of us pouring sweat in the summer. We had to wear masks to keep from breathing the crap in too.
Sure hated the stuff back then as insulation, but sure wish I still had tons of it lying around like back then at the construction site. You could barely get your arms around these monster bags..LOL!
