Best Museum Exhibit Ever

At the Henry Ford Museum in Dearborn, MI, they have a collection of some of Henry Ford's favorite things. (It's in between the bus that Rosa Parks refused to give up her seat on and the Oscar Meyer Wienermobile.) The collection includes the chair that Abraham Lincoln was assassinated in and George Washington's trunk with his personal effects from his days as a general, including a folding bed; however, my favorite thing is the corked test tube containing the last breath of Thomas Edison.
