Hi, I’m Sarah McDaniel, but most of you will know me as Krotchy. What you might not know is that I’m also a scientist. Here on Collide I’m going to be bringing you along with me as I learn more about the world around us, and discover what secrets lie within it. I’ll be uncovering facts, speaking with experts, and discovering the real truth. Come Collide with me and we’ll both learn something new every day!
