These days, if it's not one thing, it's your mother.
Mine decided she needed to supplement her attic insulation with 4,500 cubic buttloads of cellulose insulation. (the fancy words are a lie, cellulose means shredded up newspaper)
In August, in the warmth.
The unconventional wisdom being, that if you insulate the attic while it's 100-plus degrees outside, that heat will be trapped there so that it can keep the house nice and toasty in winter.
So I got to clamber up there with an extended-range fluff bazooka and blast away at the rafters for 3 hours.
Before the dust started, it was a silent gray snowfall.
THIS is the power supply for fluff-blasting. It requires two able-bodied persons to stand over it and crumble the bales of cellulose into manageable chunks. During my turn at this, I discovered the work goes by more pleasantly if one sings, "Crumble crumble crumble crumble crumble" to nearly any tune that comes to mind. Sadly the vocals are not included in this recording.
