Danny became more acquainted with the 16' measuring tape. While we were outdoors testing the wooden glider plane, Danny would ask similar questions related to height; "How tall is 4', 5', 6', 7'..... and so on. Each time, I would illustrate on myself, a tree, or perhaps a playground member where these various measurements might fall. We then went indoors and looked up on the internet, how tall the tallest person is in the world. The answer was 8'3". Danny really seemed to be inquisitive about this whole endeavor.
