COSI is an acronym for “Center of Science and Industry.” I always think of this as a Children’s Museum and I think this is primarily who they cater to; but there is certainly plenty to see and enjoy for us adults, too. Of course, a lot of that enjoyment is watching the reactions of the kids to different things.

This is the entrance of COSI with the pendulum which swings and knocks off iron balls. We had 19 of us, including our driver, Joel Harbaugh, and his family. Thank you Joel for driving.
Many, perhaps most, of the displays are interactive. These range from biology, to physics, to ecology, etc.
I think I had a couple of areas that rated as my favorites. The top of the list was the “Progress” area where we journey back as far as 1898 to as current as 1962. I liked the Diner and the Disk Jockey. Those bring back some fun memories of my high school days.
There was also an interesting outdoor exhibit area, called “Big Science Park,” that included a tiny concept house that is only 100 square feet and could support one or two people. It was totally green with solar power and heat. It included a tiny kitchen, bathroom and living area. I couldn’t figure where anyone would sleep but I suspect it was something like a murphy bed. It might be nice as a cottage in the woods but I cannot see it being used as a primary residence! I wasn’t sold on this concept!
I also enjoyed the “Extreme Screen Theater” with a nice 3D movie about Surfing in Tahiti. I think I need to go visit! Tahiti, again! 
Another highlight for everyone was the Rat Basketball Game. Yes, you guessed it correctly. They have rats that play basketball!
An area that most of the kids seemed to enjoy was the “Highwire Unicycle.” Our own Seth Harbaugh was brave enough to give it a try!
Although our group for this event was small, our enthusiasm for the activities and sights was huge!
