When I asked what their favorite things about the microscope were my 6 y.o. immediately said, "It's really cool because it tells you neat stuff about what you are looking at." My 4 y.o. said "I don't know, why are you asking me that." You win some, you lose some. I do believe that Discovery has a winner here, I am sure it will be on lots of lists this holiday season.
