playing with time
"Playing With Time takes visitors on a journey to the unseen world of natural change and shows events that happen too fast or too slow for humans to perceive." At the website of the current exhibition at the Science Museum of Minnesota in St. Paul, you can watch an eye blinking (5/10ths of a second), the tide going in and out at Cape Cod (14 hours) and the formation of the continental plates (240 million years).
