I have been so bored I've been sorting out my piles of receipts
. It's odd how quickly the pile of receipts grow 
And I was wondering how to get rid of (safely) them without using my extremely noisy home shredder which only does 3-4 at a time without getting jammed, or using a pair of pinking shears.
Then I had the brainwave of putting all the receipts into a basin of water, leaving them to soak for around 30 minutes. I drained the water and then screwed the whole lot into a huge sodden ball which I put in the bin!
I defy anyone to get any info out of that
