Since CRISPR is so easy to use and can produce dramatic results—such as changing human T cells to kill pathogens or modifying the DNA in pig organs so that they can work in human bodies—it's natural that biohackers would want to use it. And despite fears that the powerful CRISPR could engineer super viruses or warp the human genome, the tool isn't all that easy to use—at least not yet. "There is nothing in these kits that is harmful to your health," Zayner writes on the Indiegogo page. "The bacteria are less harmful than bacteria on your skin and the yeast are almost identical to the one you use when cooking." Plus, novice biohackers probably wouldn't know how to make the genetic changes that a species would need to infect or affect another, he adds.
