Once you find your large globe, I suggest you get someone to engineer a
gimbal mount for it. http://en.wikipedia.org/wiki/Gimbal
I think that could make a very appealing interactive exhibit (quite apart
from the geographical interest of the globe!). The designer will need to
eliminate finger-traps and maybe incorporate rotary dampers because
children are going to try to spin it just as fast as they can...
The low-budget solution would be to buy a large terrestrial-globe-beachball
half-enclose it in a box with a large hole in the top and float it on a
cushion of air from a blower, rather like the heavy stone Kugel balls that
'hover' above a thin film of pressurised water.

Give people facts and you feed their minds for an hour.
Awaken curiosity and they feed their own minds for a lifetime.
