The soft 100% ring-spun cotton Thorium T-Shirt blends both your favorite thunder based deity with your enduring love of chemistry and the Periodic Table of Elements. I wonder what your favorite element is...wait, I know! THORIUM! I have no idea how I was able to guess, that's for sure. You do have to appreciate how dense Thorium is on the molecular scale...an atomic mass of 90; my guess is the element almost works as hard as the God! Study mythos and chemistry at the same time with the Thorium T-Shirt!
