Yellow Ibis Science t-shirts
There are a number of science t-shirts you can get out there. "Talk nerdy to me" and "I [heart] my geek." and so on. Yellow Ibis has shirts that say things like "I [three neck flask] chemistry" and a skull and crossbones with the crossbones replaced by pipetors, and this really cool glow in the dark benzene ring. Or for the geologist in your life, "I date rocks." Or for a more all purpose shirt, "I blinded me with science." Yeah, I could spend most of my paycheck here. Easily. Or you could spend most of your paycheck here, buying shirts for me. Hint, hint. I'd list individual shirts, but the site is not ThisNext friendly and I have experiments I should be doing.
