Well, whadaya know. Tomorrow is Earth Day (shouldn't every day be Earth Day?). Our very own Jill Harness wrote a neat post over at Inventor Spot about 8 weird but Earth-friendly products you can buy to celebrate.
I particularly love this one: the thermoscope earrings by LeeAnn Herreid. Like a thermometer, the earrings register temperature changes with red alcohol that rises and falls (but without numerical values). So while you don't know exactly how warm the Earth has gotten with global warming and all, you can still look pretty hot wearin' em.
