In this episode of Tiny Show and Tell Us, we cover squirrel pox — a disease that hasn’t had a huge impact in the United States but has decimated populations of squirrels in the UK. Then we talk about the story that Napoleon's army lost the Battle of Waterloo because the military uniforms used tin buttons that broke apart in cold temperatures, making it harder for the troops to survive. But is there any truth to that story?
