That biohazard/DNA scarf is awesome! And, looks like I might be swiping a few of the plastic petri dishes from my closet at school to make myself a set of coasters
The test tube windchime is a great idea, too!
Again, my favorite swap so far!
PS And, the clock gave me fits, I tell ya'! But, I have a bunch of keyboards that you can rip apart if you want one of your very own...
PPS Are those chromsomes peeking out of that right-most teaser pic chilledsoup?
And an afterthought (since PPPS just seemed waaaay too junior high
): The Fibonacci pillowcase is leading to a combined Math/Science/Art assignment with some of my students!
