Visited the Museum of Science and Technology in Chicago. Here are a few shots of interesting stuff.
Quite the fantastic locking mechanism.
Then there was your basic tornado vortex machine. Everyone’s got one.
This was a 20’ spinning disc filled with colored sand. As it spun the sand continuously slid down the face creating ever-changing patterns. It was hypnotic to watch it for a while.
Love a good indoor dive bomber.
