It would be Iridium and if you need a small sample of it, they use very very small amounts of it in spark plugs because it supposedly produces better spark and combustion.

send link to picture, I'll check it out.  Also, try Ebay.  An item is only worth what people are willing to pay for it, and that'll tell you what they're willing to pay for it.

Do something that the judges can learn from.  Those are always winners.  For example, some one the projects that won in my location are:  Who makes the strongest fishing line?  Out of all the towns in you county, what town has the cleanest drinking water?  What color of roof keeps a home the warmest/coolest?  You can find some good ideas off of the internet.

I think collecting it in the first place is going to be more tricky!  Do you ask friends and family first?\n\nhow about using a giant cannon?

I'm also doing an environmental project (school). I found lots of interesting stuff by asking the people around here. Try that but don't say it's your homework or something.

have everyone bring a gift and just put Lady or Gentlemen on the tag. have food of course as this is primary importance and liquid refreshment. if liqueur is served have cokes or non alcoholic drinks also as some may not want alcoholic drinks then have a picture cut in two pieces one half for a lady the other half for a gentlemen when the two haves are found these two would be partners for a scavenger hunt.

Find a question that relates to the local area you live in, something you may have noticed, or has controversy.  A saying I like is "One measurement is worth a thousand expert opinions", which is the essence of science.  So find something to measure.  When I was in school (a long time ago) people I knew wondered about whether the local creek was clean enough.  Kids played in the creek and some people fished in it, but I thought it shouldn't foam and have a not quite clear look.  So, I got some sterile petri dishes from the biology lab, got some q-tips, and talked the local hospital pathologist into helping me.  If you need help, ask, you might be surprised, it turned out he was curious too.  Anyway, I learned a bit about how to identify bacteria and yes, the creek was polluted-bad!  I made the front page of the local paper.  I'm not saying do this, but think of a local problem and measure it.  Hope this helps.

For a little joke: Find a truncated icosahedron.  The scavengers can fulfill this requirement by bringing back a soccer ball.

tolga party (everyone is dressed in sheets... and for fun you could be wearing one with sponge bob or some dumb superhero you loved as a kid) pizza is always a favorite even though it is NOT greek :)... give a prize for the best dressed (cash gets people's attention... maybe $20)\nOR....\nif some of your friends are also old enough to drive have a scavanger hunt. each car has 4 kids in it and each car has a set of riddles they must solve and drive to in order to pick up proof that they found the answer... if you do this one, you can do the whole CAR theme and serve anything you want to eat... (probably like pizza hehehe)

If it is a mobile park then there should be lots of options to choose from. If there is someones address that is say 6561 Kennedy Street you could leave a clue that has to do with the address.... "I bet KENNEDY knew what 9*9*9*9 is"... 9*9*9*9=6561 or else you could chose items with riddles. If someone who is participating has garden items in their yard like a well you could leave clues along the lines of "jack and jill went up the hill to fetch a pail from here" ...you just have to be creative. We used to do this all the time for Christmas in my grandparents house. We always used clues like "the next clue is in the coldest place in the house" (freezer) etc....if you need more specifics let me know.
