Pringles pot as form for small secondary

[Hhchicken1-at-xxxxxxx (by way of Terry Fritz <twftesla-at-xxxxxxxxxx>)]

</lurk mode> 
I've been following the sonotube thread, and wondered if a Pringles pot is 
made of a similar material - would it make an acceptable secondary for my 
first coil (a tabletop model)?  I wonder how lossy it is, as PVC or similar 
pipe with a ~4-inch diameter isn't too easy to find :) 

Any ideas?
