Yes, I have made a small bank of rolled capacitors this way.  Each one
measured out to be about     1.3 nf.  They are _extremely_ dissipative, I
was tempted to use them as foot warmers;)  After a 15min run the plastic
gets so hot that they failed with around 15kvac.  The only way I could
get them to last a while was by leaving them in the bottle shape and
making salt water caps.  The salt water kept them cool for a decent
amount of time.  Something weird about them is that the water inside
glows a eerie blue, a effect you can not see with most beer bottles.
