'Facing Mars' @ The Health Museum

'Facing Mars' is an interactive exhibit designed to educate kids (and grown-ups, too, for that matter) on the effects of extended space travel and reduced Mars gravity to astronauts' bodies, both short- and long-term
The pic on the left is a special chamber to launch a rocket we built of foam parts. (I think it's a vacuum chamber; we had to pump a handle till it was almost impossible to move.) The pic on the right is of Aidan and me in the 4-D movie theater at the museum. It was on the cells in the lungs and immune system (not space-related), but fun nevertheless.
