I’m a physicist and engineer, and would be delighted to work with kids who are interested in science. I have been known to do “Dr. Destructo” sessions for kids (taking apart already-broken devices such as disk drives to see how they work), but don’t know if I could get the tools onto the ship. However, some math-related crafts a la Vi Hart would be possible. Tex-Mexi-Flexagons at the taco bar, anyone?
