The picture is of the 'falling' machine. They strap you in and then tip you back while a camera records your fear response. It was interesting to see everyone flow from anxiety to startled to joy. Everyone who 'fell' ended with a huge smile on their face.

Bayley enjoyed big-boy time, playing with the friend he brought and another who happened to be there (both from his last school).
