I bought some flexible aluminum ducting that was claimed to be 8' long
but of course was "collapsed" when I bought it.

Is there some special trick in stretching this stuff out to anything
approaching its specified length? I only need it to stretch to about 5'
long, but it just seems to keep "unraveling" -- coming apart where the
"turns" overlap.
