Go with American vintage. You know, metal plates and advertisement of the 1950s. Maybe not cigarette related, but automobile related. Car license plates are also a nice idea. If that doesn't help think about an American sport. Baseball or Football.

I think the most revolutionary invention of the 20th century has (go ahead and laugh) the perfection of the bidding rules for the card game "contract bridge" in the 1930's, because it represents a NEW FORM OF LOGIC which we will see in chaos theory and advancede mathematics over the next 50 years or so.\n\nWhat changed our fculture the most?  Physically, the automobile.  Artistically and intellectually, television.\n\nFor the 21st century, I think a form of artificial intelligence will emerge before the end of the century as the most revolutionary invention.  I think the end of America as the world's superpower will change our culture the most.\n\nIn the 20th century, I think the importation of German philosophy into our arts and culture following 1945 detracted more than any other thing.  But the modern focus-group, polled and surveyed political manipulation in elections and politics is a close second place.\n\nI think the major detraction from our culture in the 21st century hasn't even started yet.  I can't guess what it will be.

make anything out of the following\nperiscope\nvolcano (Although I don't suggest this - it is a very old project and maybe many will turn up using this)\nA mini hovercraft or hot air baloon (info can be found on net)\nI don't know what it is called but if you know that thing in which we have to take a small hoop across a wire (which is not straight) without touching it. If touched, it will make a sound.\n\nIf none of this suits you, you might watch Backyard Science at National Geographic Channel
