Roller Coaster

 At the Bishop Museum right now, the rotating exhibit is about roller coasters.

 Right up front there is a 1/20 scale coaster called "the Black Plague."  In real life the 9~ Gs would put you out cold, but in miniature it is just hand-flappingly awesome.

The model has a timer on it, so the car will only launch after a three minute break.  There is nothing he will wait 3 minutes for, except to push the button to start the ride.  And he'll do that as long as we are willing to let him.

There are some other hands-on demonstrations of the physics involved, as well as a large screen that plays video of several roller coasters set up with feedback chairs to simulate a ride. 

But after a couple minutes exploration we always end up back here.
