Engineering Day

The National Building Museum had the engineering festival for kids yesterday. We stopped in to see what it would be like. Their were so many cool exhibits by AIAA, NASA, ASCE, and many more. There was a place for kids to make paper rockets and launch them. Finn made a paper helicopter and let it fly. The agricultural and bio-science folks had a popcorn display that drew tons of attention. Here a guy explains lift through the use of a broken wind tunnel.


Finn asked a brilliant follow-up question about Reynold's number and transition from laminar to turbulent flow that left the guys speechless. That's when we moved on to the chemical engineers. They were mixing up slime for the kids. Finn got a bag of blue slime and brought it home.



It's just water, borax, and Elmer's glue, but it was Finn's favorite thing he got there. I suppose there's nothing wrong with being a chemical engineer, but everyone knows that the cool engineers are all probabilistic mechanicians.
