Just in time for the Easter Holidays Walkers are offering half price tickets to Chessington World of Adventures Resort and the 12 SEA LIFE aquariums and sanctuaries across the UK.
Preheat the oven to 175 degrees (without the fan if possible)
Place a layer of silver foil over a cold baking tray
Iron your crisp packet (I put it under a towel)
Place the crisp packets on the tray and then place in the oven
Watch as they miraculously start to shrink (you think nothing is happening and then POW all of a sudden they start)
As soon as they stop getting any smaller remove from the oven and place a heavy book over them to ensure they stay flat
I punched a hole in the packet before placing in the oven for the one we turned in to a keyring. We then put an old keychain through the hole.
You could also make badges by gluing a badge back to one.
