As a child I remember the whole family saving the aluminium milk bottle tops for Blue Peter appeals. I'm wondering how this ever raised any money. Was the price of aluminium huge 20 years ago compared to today? It seems to me that you would have to save hundreds of tops just to get the same amount of aluminium found in a coke can. Maybe all cans 20 years ago were steel. Even so wouldn't it have been much faster to save used aluminium baking foil than tiny bottle tops?
