Stand Back I'm Going To Try Science T-shirt "Stand back! I'm going to try science!" with a little figure holding out a flask and a calculator in white on the front of this black 100% cotton t-shirt. We love the verb on this shirt. It could have been "do." It could have been "perform." But no. It's "try." Which is so unsure. As a wise figure once said, "Do or do not. There is no try."
