LOL
I thought she was stretching the pantyhose over the computer to cover it and keep the dust out???
now I'm confuzzled

I'll admit to using our shop vac with the hose on the blower side and blowing out the insides and keyboard of my computer ..
but I kept it pretty far away from the case cause it blows pretty strongly.

Dust sure went flying everywhere..
then I switched to the vac side and caught most of it while floating in the air...I hope anyway...
