Ah see I think we saw that Ikea insert thingy but because it was called a Clooganthok (or some other random arrangement of letters - no disrespect to Swedes, I'm sure it all makes perfect sense in Swedish) we couldn't work out what it was for. Anyway thanks for your replies, I think we'll try it at the weekend (when hubby is around for reassurance/equal blame) although that random backward flinging sounds slightly worrying....
