A rainy Saturday afternoon is well spent at the Exploratorium in San Francisco.
This is neat; you can experiment with principles of sailing using big fans, and small carts on wheels with adjustable sails.
A large pendulum produces a wiggly sand trail along a conveyor belt.
Try this: put together a small puzzle, then try explaining for your puzzle buddy how it looks, and see if it can be copied...through words.
howling into the echo tube
sticking my camera into the endless mirror
Truly an exciting visit!
