You might expect to see a bubbling green potion or a black widow when you first enter the Denver Museum of Nature and Science’s (DMNS) newest exhibit, the Power of Poison. Instead, you’ll find a bowl of chocolate candy and a pile of salt. “Basically everything is poisonous depending on who you are and how much you have of it,” says Jenna Chervin, the museum’s educator. “Chocolate isn’t poisonous to us, but it’s not great for your dog. Salt is really important for our diet, but you can’t have too much of it.”
