Finally, A Science Fair Idea

AT LAST!!! FINALLY!!!! My brain finally decided to get up and start thinking, the result? A Science Fair idea!!!! Hahahahahahahahaha I felt so proud of my brain, then I hit my toe on the edge of the coffe table and suddenly didn't feel as smart. :/ BUT WHO CARES SINCE I GOT AN IDEA!!!! Tralala, hahaha, trallala~~~  In case you're wondering that's the happy dance song. :) Let's look at the history of my brain's ideas for this year hm? First I had the idea that I would do the effect of caffeine on people but then my science teacher said "no experiment on people >:|. SO then I got the idea to do something with stains. But that just seemed so common... But then, while I was eating delicious chocolate, I came up with the idea that saved me, how much pollutant different types of soil absorbs! I know, it's not exactly exciting but as long as it's not put me to sleep boring and not too common, it's good enough for me. >:)
