For all of those out there who perform Extreme burn apart from changing things into cash ie magazine clippings, receipts, bill, kids hand drawn notes and smaller bank notes/bills to higher value bank notes/bills etc have you used the gimmick to change somethingin to something else other than cash and if so what ?

Good, relative question warren ...
UK bank notes are all going plastic ... so WHAT do people use?

I would be surprised if this routine is not performed so much in the UK any more.
Could be wrong, though.
