The Denver Museum of Nature and Science just ended a temporary exhibit on the Power of Poison. As part of the exhibit, there is a live show based on an historic murder which helped launch the modern science of toxicology. (If you are interested in reading more on this, check out the book The Inheritor's Powder by Sandra Hempel.) I had the privilege of being one of the performers for the show. During the show, we gathered volunteers from the audience and simulated what would happen to a person who ingested arsenic. We then had more volunteers help in an experiment to discover which of several suspect samples contained the poison.
Your local museum is an incredible resource for learning. If you have not visited yours recently, take the time to find out what they are doing. Who knows what new and exciting things you'll discover.
