Homemade Reverse Jelly Roll Capacitor

  Hello there. I'm currently using a capacitor made from foil tape and 
semi-clear plastic bags used for holding  fruits and veggies. The foil tape 
is unpeeled from the wax paper for easier handling. I wrapped layers upon 
layers of bags around a length of foil tape then put another length of foil 
tape over it. After that, I rolled it up like a carpet and held it with a 
rubber band. It's compact and has a higher capacitance than 6 bottle caps. 
I knew about the inductive effects so I rolled the two layers
in reverse midway in order to create two counteracting inductances. I'm not 
sure if this is effective in canceling the effects. Inductive effects 
aside, this seems like a very cheap and compact way to make high value hv 
caps. Any thoughts?
