Just a quick question: *Why* would you want to dissolve it in the first place?

If it is only about rendering it unusable, how about a nice oscillating magnetic
field? Microwave oven? Using a strong hole punch axially on the spool to convert
it to confetti? Cutting the spool in two halves using a strong paper cutter? ...

Or is this a new attempt at data compression - dissolving the bits, to later
distill them into a concentrated powder? :P
